There's no ideal solution. No utopia for you, sorry. Not in your lifetime, or in a lifetime of your kids. Only thing you can do is to steal/earn enough for yourself and those that are close to you, and live happily ever after in some remote corner, as far as you can be from any government. People are competitive by nature, they work in their own interests, and there are too many people with too many interests. It's logical that given the power you usurp that power. If someone is delusional enough to believe in some greater good, this is only a stage in his life, until a point where his delusions are replaced with common sense, coming in terms with his needs.
Unless the entire generation of youth believes in the same delusion.
A question: once government is out of individual control, how do individuals stop it from evolving into fascism/communism without taking control of it again?
Anarchy, complete nature and balance.
Even if you raise all that generation as your kids, teaching them to be good and all, and giving all attention needed - there will be conflicts and it will go out of control. People will fight for money, for power, for space. It's human nature.
If you altruistically give give and give, there will be those who'll get used to take take and take. You will get tired of giving it to people like that, and stop - they will get angry at you for stopping, and fight among themselves for scraps, or even attack you. If we build something together, one of us will get tired/annoyed/bored faster than others and will sabotage our hard labor. If one of us works harder than others, he would want to receive better payment than others.
Only possible way would be to clone same guy over and over, and brainwash him - so there's uniformity. Unachievable otherwise.
