Surely, all political systems are designed to exploit....including Libertarianism and Anarchy.
Libertarianism (the ideology) is not a political system. It does not provide a specific solution or form of government/governance. It stresses individualism and the non-aggression principle.
People can feel exploited, whether or not they recognize a particular system as the cause, but we as rational beings (or those of us who consider ourselves rational), do not shout curses at storms and disasters for 'exploiting us'.
Some people who claim exploitation or accept the title of victim are looking for someone or something to blame.
I will no longer promote libertarianism to other people that I come across. It's not because I don't care about people (which I don't), but it's because it's just bullshit...like pretty much everything else.
In this case, I must stress that the perfect is not the enemy of the good. It is not beneficial to expect absolute truth, nor is there any lasting comfort in its opposite: Nihilism. What I would suggest is that you try not to stress out too much about this and consider that we experience this life from a limited perspective, and while we may see the world as imperfect, it's certainly not something that has to mean we will always be unhappy.
It's just a given, but if we believe we are volitional beings that can make a difference outside of the mindlessness of collectivism, then we can start to build meaningful relationships and take substantive steps towards a world we want to be a part of. The realm of value is the realm of the individual, and in this perspective of the universe it is not the absolutes we should relish, but the _informative_ truth.
