Just as more mouths to feed means more hands to feed them, surely fewer hands to feed mouths means fewer mouths to feed. It balances out. |
What you've said makes no sense. The human civilization benefits from the economy of scale:
it takes a billion people to produce an iPhone. Not all of them work on it directly, but all jobs are interdependent. (Someone has to grow the rice to feed the worker who mines the iron ore to make the metal in the car that an accountant drives to meet with a client who makes sex toys that encourage a secretary to work overtime helping a lawyer enforce a contract on a software development consultant who programs a robot to manufacture shipping containers that are used to transport medicine that is needed by a ... you get the idea.)
Furthermore, there is a benefit of having more inputs in any natural selection process. I'm not saying it is impossible for Liechtenstein to beat Germany or Brazil in soccer, but it's highly unlikely: those larger countries have a lot more soccer players competing to play in their local playgrounds, high schools, colleges, amateur teams, minor leagues, major leagues, and finally the national team. The same applies to all fields of human endeavor:
statistically speaking, the IQ of the smartest person within a population goes up or down depending on population size. The more people you have, the smarter are the super-geniuses you have to make huge innovative leaps forward.
This still doesn't explain why I have an enforcable duty to have kids. It is for the good of the human race that some people reproduce, sure, but (a) why does that mean that that somebody should be me, and (b) I scarcely benefit from that anyway. |
(A) I didn't say you have to have kids yourself, I've said you have a moral obligation to contribute to the next generation.
You can pay others to fulfill this obligation for you.(B)
You don't benefit from repaying debts, you've benefited from debts when you acquired them, which in this case was when you were born.Damage or injury. In this context we are talking about an unnatural action that causes damage or injury to the rights of other entity or entities that possess natural rights. In this case "unnatural" means: contrary to the reality of being prior to your intervention.
If I didn't have a shotgun wound in my head and your actions caused me to have one, then you have violated my right to life, even if your shotgun went off by accident. If a million people didn't have pollution in the water on their property and you put it there, then you've violated their right to property, even if it was through inaction, like failing to re-enforce storage containers containing nuclear waste that deteriorated over time. Etc.
Reproduction is a fundamental part of human nature, and your existence is a consequence of millions of your ancestors who've acted on this nature. Your unnatural failure to perpetuate this cycle of life causes economic damage that grows over time. It is comparable to hiding a robot somewhere underground that is programmed to activate sometime in the future, dig itself out, and release a virus or otherwise do light economic damage to a large quantity of people.
Only presuming we have a duty to reproduce at a certain rate that can be enforced. |
Look at history. You will see this duty encouraged (and at times violently enforced, but that's really not necessary) through cultural values in Christianity, Confucianism, and other cultures that have stood the test of time. And you will see the failure to enforce those values in cultures that have collapsed.
The same argument that backs the triumph of capitalism over socialism also backs the triumph of rational natalism - a culture that discourages willful failure to reproduce.
But that is precisely what is in question: There is no such duty. It may be charitable of me to reproduce 2.2 times in order to help ensure the survival of the species, but forcing me to violates my ownership of my body, which is an injustice. |
Imagine a socialist saying: "Property rights do not exist. It may be charitable for me to respect your property if I like the way you manage it, but forcing me violates my right to access the same property, which is an injustice."

You can't make an effective argument by just stating your opinion, you have to demonstrate the rightness of your argument by objective means, like through a valid experiment. Unfortunately in our case a complete experiment would have to last hundreds or even thousands of years, so we have to extrapolate from smaller observations, historical examples, and common sense. You would have to refute the following claims:
- At this time human beings are still mortal, and new human beings can still only be created through biological reproduction, which requires a particular effort, discomfort, and risk on the part of the mother. Furthermore, effective transition of newborn infants into adulthood requires a substantial commitment of time and money by someone (i.e. parent or guardian).
- Fertility rates are declining in all parts of the world, currently averaging 2.61 worldwide but falling quickly. For now the biggest problem resulting from this is a demographic-economic paradox that results in decline of average human IQ rates and other negative consequences. In the future, it will also result in the decline of the total human population.
- Declining population is causing measurable economic harm in places like Russia, the rest of Europe, and Japan. Some of those harms are mitigated through import of goods, services, and immigration of people, but (unless we discover an extraterrestrial civilization) that would not be possible once world population as a whole begins to decline.
If I don't reproduce, on the other hand, nobody's rights are violated. |
What about the "suckers" who do reproduce: they spend a huge fraction of their time and money to have children. The vast majority of people who reproduce in the first world do so out of a sense of obligation that you do not share. Most of this ideology is religious and is in decline, along with the birth rates. And survival of everyone does depend on people continuing to have children. You were born, and so was everyone you've ever done business with, directly or indirectly.
Willful failure to reproduce is harming the human species as a whole. I know this sounds like an appeal to altruism, but it isn't - altruism is economically harmful, while rational natalism is economically beneficial, perhaps even essential. I know this sounds like an appeal to collectivism, but collectivism is beneficial in some particular cases, and this is one of them.
It might not be nice for the people who would otherwise have existed that they are not going to now, but then they woon't suffer from that because, hey, they don't exist. |
People who don't exist don't have rights. (Duh!) I fully support the right of contraception, vasectomy, abortion, etc. But
you are obligated to pull your own weight, economically and biologically. To live and to refuse to reproduce, expecting others to reproduce for you, is theft! It is no different than a government "welfare" program that is funded through inflation: everyone experiences economic harm for the benefit of the lazy.(Gotta start dinner, will reply to the rest in a little bit.)
