Stopping accumulation of power is very hard when you have no accumulated power. I’m not sure how you could possibly believe otherwise unless you’re one of those believers in magical harmonious anarchy
So when you have $10 and your neighbor has $200 in whatever assets or currency your little community needs, and your neighbor decides to invest it, you’re gonna what, attack him? Gather your other neighbors and demand he share?
I don't consider myself an anarchist, partly be cause the term has been repurposed so many times now that it doesn't have a clear meaning.
The belief in magical harmony is unrealistic regardless of the model that's supposed to create it, whether its anarchism or federalism.
