You haven’t listed anything unique to socialism. Capitalism also works well until you’re poor and don’t want to live right next to, I don’t know, a bitcoin mining facility or something. Authoritarians are the ones running down dissidents with tanks and spinning up concentration camps, not their economic systems.

And you don't think that an economic system that denies every aspect of freedom (down to, and including the freedom to decide what, or even whether you get to eat, what you wear, where you'll live, what your job is, etc.) can possibly exist without also introducing a very hefty dose of authoritarianism?
