The more people there are, especially in close proximity to one another, the more restrictive the environment becomes.
People generally don't like each other very much, and if you're doing something I don't like (whether or not it hurts me) I will try to put a stop to it, sometimes just out of spite. I can make a case for almost anything you do being harmful to me. Multiple this sentiment by a few hundred million and you're well on your way to oppression.
If people were truly rational we wouldn't be having this discussion but unfortunately emotions get in the way.
Ok, you both either completely miss the point, or you have just been indoctrinated so completely that you feel it is impossible for free people to live in an ordered society with laws conducive to the living conditions and population density without surrendering their rights and property to the collective, or you are a collectivist in which case I’d have more luck talking to the wall, but we will just have to agree to disagree and I’ll wish you both good luck either way.
