Anarchism has failsafes for this since hierarchical structures are by definition not welcome.

How does it enforce that unwelcomeness? As much as I ideologically align with anarchism in principle, I don't see the mechanism for it to preserve what is and isn't "allowed" under it's principles. Especially not the ad hoc, spontaneous, nominal anarchism that would result if you burned the current system to the ground.

What stops a charismatic figurehead from rallying the portion of the population that finds authoritarianism comforting, and starting their own fascist hierarchy? The current system may not be perfect, but at least the checks and balances provide some obstacle to despotism. What do you replace that material obstacle with? "Hey! You're not supposed to do that!"?
