Maybe you haven't read Marx's work. Maybe you haven't studied his thoughts. Marx was quite an anarchist even though he didn't get along with the anarchists of his time and was too focused on party politics which was a mistake to me, but he had hope that the bureaucratic and military state would dissolve eventually under communism. Of course he was wrong because authoritarian monsters always avoided losing power. Any humans given some power become authoritative, or at least that is what it looks like through history.
Your ignorance about this is quite common from libertarian dogmatic people. This is what you are taught. Communism bad, evil, wrong, crap, whatever. But your critiques actually have intersections with communism. The most important one is the disapproval of parasites in society. For communism, the parasites are the capitalists. People that inherited wealth, people that take the value generated by others and increase their wealth by such exploitation.
So to you the parasites are only in the government and it seems that banks too. However, communists note this parasitic behavior in rich people who don't produce anything but just take advantage of the work of others.
So, yeah, I see how government can be parasitic, I see it in the country where I live. I also disapprove banks role of monopolizing debt and money. And I also disapprove any person that profits from the work of others. This last one is the only thing you don't mention in your text.
Part of the dogma you've been teached is that capitalism has worked wherever it has been seen. But I don't think you have any evidence on such claim. Never mind, that is just part of the "capitalism good, communism bad" dogma.
Definitely, soviet communism, chinese communism, cuban communism have failed in many aspects. I don't think that needs to be debated at all. I think every human systems is alwasy failing and it seems like we are just discovering that. And there is also dogma in some communist people, mostly about having hope on the figure of the state and also thinking the basic claim that "communism good, capitalism bad". It is very similar.
