The problem is : there's no solution. Capitalism = pseudo freedom. It always ends up with ppl beign in classes (rich/poor). Anarchy = real anarchy can't work, they'll always be a leader at some point. commuism = it always ends up corrupted. Now if you reduce humanity to 500 ppl and teach good values. You will need to have control over these ppl so they dont go corrupted (as human becomes corrupted by nature), and then they're not completly free. And at some point you will have 1000 ppl on the island and you will need to expand since getting back to 500 would involve killing 500 (and controling birth is a kind of opression over one's freedom too). now you will have to expand and expand and finally get to millions of ppl and loose control and eventually get back to the same point : 6 billion of ppl that can't organize themselves because of corruption. Now you can find a way to modify human's nature to make them so they're always happy never angry and never corrupted. Make them so they can't hurt others, things like that. Then it would be perfect communism. BUT it wouldn't be freedom : evryone will be forced to be good even if they dont want to. There would be no diversity, no difference between ppl. And when you get evrything right, humanity will live forever. It'll be kind of : now what? we reached our ultimate goal what do we do we can live our lives, ok, but now what's humanity goal since survival isn't a problem now? evryone is identical so no genius so no research and then bye bye that need for exploration we always had. So still there we would end up like a machine that can stay on forever... with no freedom.

There's no solution, to be completely free, you have to be alone... but nobody likes to be alone, isn't it?
