I am pretty sure the proposal is not banal "anarchism" (the complete absence of top-down governance), but instead
anarcho-syndicalism, which is not the same thing at all.
I would argue however, that any system that (through design or otherwise) prevents the formation of a majority (and thus, a ruling body of some form), is inherently impotent to assure or enforce anything. A majority demographic is still a ruling demographic, especially if you are a member of the defacto suppressed minority demographic.
RE: Biden, The executive branch, and sending JackBooted Thugs to Portland
The timeline speaks for itself. When the protestors were in charge of that scene, and before the agent provocateurs started causing trouble, it was surreally peaceful there. We are talking "We brought snacks!" levels of peaceful. Then, plainclothes police started causing trouble and blaming it on the protestors, instigating the fed to send jackbooted thugs, who started shooting the place up, and shooting innocent bystanders with rubber bullets, not to mention actively shooting members of the press the same way.
This has been a demonstration of every possible way to NOT handle a protest, while clutching your pearls and shouting about how lawless those people are for the violence that you are causing. (you in the context of the government) This is some shit straight out of some Aldous Huxley, George Orwell, or Ray Bradbury novel right here. (though mostly Orwelian)
