I know full well the joy of being unproductive because capitalism affords me the ability to do it. It's expensive and requires an amount of agency only afforded by a high income or outside wealth.

Do you really think the authoritarian elites will let the unwashed masses with no income do whatever the hell they want? Can you really say that after COVID lockdowns demonstrated their true colors?

None of the other capitalism-alternatives have historically afforded the kind of luxury you're suggesting either. Quite the opposite, in fact.
