Just because reaching a true utopia is not possible, it doesn’t mean we should settle for an economic system that is literally destroying the planet.
Despite what both conservatives and tankies want everyone to believe, marxism and comunism are not the same thing.
All marxists are communist, but not all forms of comunism are marxist, there’s also anarchism, democratic confederalism and libertarian socialism.
Utopias don’t exist and never will, that’s why Marxism, and by extension communism, is such a colossal failure.
