Because you are just as exhaustingly childish, naive and deluded as the Randistanis, who believe destroying the government will suddenly lead to perfect freedom and prosperity.
I don't believe any of that, actually. I do believe revolution is necessary for Humanity to move forward, but not that it would immediately lead to perfect freedom and prospertity. That needs to be built, and it can only start by the proletariat siezing the Means of Production and wiping away the old Capitalist state.
The rest of your comment is gish-gallop historical revisionist nonsense.
No, it has not. Read Blackshirts and Reds, which I already linked. Communist movements served the Proletariat, not the Bourgeoisie. They also were by no means perfect "worker's paradises." Another good article is *Why Do Marxists Fail to Bring the "Worker's Paradise?" if you can only spare 20 minutes and not read a whole book.
You should read On Authority, Marx and Engels were constantly hounded as "authoritarian" for advocating for central planning.
