Your anarchistic beliefs are totally naive and unrealistic — even if one agrees that governments are inevitably corrupt and large governments tend to fight one another for economic or other reasons at terrible cost to humanity and weaker nations.
Communism actually had, in its “scientific socialist” ideology, probably the most thought-out road to a utopian international future. They thought a future for humanity without the need for “force” or government was possible — but recognized that it could only happen in stages. Unfortunately, their ideology, especially when it assumed a necessity for a transitional “dictatorship of the proletariat” … proved to be a rather vicious “God that failed.”
Especially because it triumphed first in backward Russia, where it actually for awhile gave new life to the collapsing Russian Empire, it proved ultimately a failure even on its own terms. That empire continues to collapse. I have no expectation that China will succeed where the Russian empire failed, even though in theory it might seem not to be burdened by old fashioned imperial oppression of more advanced subject peoples, wanting their own freedom (Eastern Europe, Ukraine, etc.)
In any case the interconnectedness and competitiveness of world economy makes modern anarchism an outdated much too localized concept. It might work for a few survivalists, but not for most in the modern world.
