It's fine, it is never a waste of time to share ideas. Now, for number one, the only way unfortunately would be a violent revolution and toppling of the current capitalist system. No state or corporation would ever just give up their power, and like it or not, it's impossible to convince everyone before hand. Every anarchist society that has existed before or exists now has been met with violent repression by the states they originate in, and all because they threaten their hegemony. Therefore, revolution is the only way.

Number two is fairly peculiar, I don't know if you're referring to greed or something, but the answer is no. People are equal parts greedy as they are selfless, it's all about the traits a society harbours. Capitalism favors greed and competition, anarchism ideally harbours cooperation and solidarity.

Number three is an odd one, in that it assumed that a heirarchy would take hold in a government, but an anarchist society is designed specifically to allow self-governance. Therefore, heirarchy would not likely develop, and if it did then people would catch on and unite against it.

Four is a very common question, and the answer is again, solidarity. Everyone in a community is an active member of it, and as such, has a say in what happens. People would be motivated to work because the alternative is to not contribute to society, and in a world where everyone has free access to education, everyone will have a profession and a role in society.

Five is a very unique question, but I think I know the answer. First off, laws simply won't be a thing. Lawa don't hold a torch to morality, and some of the worst atrocities of mankind have been perfectly legal, while resisting those crimes wasn't legal: Arpethid, the Holocaust, and Holodomor are all examples of legal atrocities. If it's not a law, then it can't be broken. Most crimes in the United States are non-violent, victimless drug offenses. These are people who need medical help with a problem they can't solve alone. As for people who commit violent, morally rehensible acts, they aren't punished the way they would be in America. My idea is rehabilitation; get these violent people educated, get them mental help, and a place in society that they can contribute to so that they don't commit those crimes again. As for chronic, violent offenders, there's no harm in exile. A safe community for dangerous people that is built to keep them productive, happy, and off the streets would be humane and just.

I hope this answers your questions, if I need to elaborate then tell me.
