So, I have asked this question of Ian Freeman, Gardner Goldsmith, and Stefan Molyneaux, - and I haven't received any answers... Therefore, I want to crowdsource this...
It seems to me that liberty lovers are in need of a simplified, single sentence principle that can be followed with regard to judging a person's capacity to enter into a contract. I think the Libertarian oath can be modified, or that some kind of similar blurb could be created...
By 'capacity', I am referring to individuals such as children, the mentally handicapped, and the insane or otherwise 'thinking impaired' individuals.
What I'm seeking is something boiled down... Its my belief that if some kind of principle that can be followed in this matter, and focused on in liberty discussions as other principles are, it would really help win hearts and minds of people that might otherwise turn away from liberty in a discussion about an issue that involves someone who is 'thinking impaired'.
Stefan asked me if I had any suggestions as to an answer to this, and really... I wish I had suggestions, but it is such a difficult question, because judgement capacity is not easily measurable - and current standards for judgement capacity are very arbitrary: Adult at 18 years old, .01 blood alcohol level, below 60 IQ, 21 to drink, 16 to have sex.... Who picked these... and why? ETC
Combining all those into a rational philosophy that people would accept and perceive as logical and functional is a question for which I don't have nearly enough information, as I don't deal with this stuff often in my daily life (not as much as you guys for sure). I suppose looking at any documentation on how the arbitrary standards were reached MIGHT be helpful, but I'm not even certain of that...
How do you codify the principle behind the force necessary to care for or corral those with mental shortcomings into something consistent rather than an arbitrary litany of nonsensical rules laid out by governments?
