Pretty much every time someone offers an extreme as a solution it’s a case of “easy answers to hard problems”. The real optimal solution is almost always very nuanced, but dumb people just latch onto extremes because they’re easier to understand.
Take farming as an example. Under the Soviet Union it was a textbook communism command system, and it was insanely inefficient with massive food shortages. But conversely you don’t want it to be 100% privatized either because then it will devolve into a few mega monopolies that just grow cash crops like almonds which destroy the local ecosystems.
Ideally there would be a combination of private farmers with government oversight to prevent negative social externalities. But your average Fox News junkie or tankie doesn’t have the patience or rationality to understand that.
