I think this is a reasonable description of what happened, and a real danger. Dogmatically gettng stuck on one set of economic and social possibilities just because they fit into the grand benevolent -ism is the issue is always fraught. It goes both ways, of course. When people say: "Oh, we can't do socialism, or anything that looks or feels even a tiny bit like socialism, because look what happened with Lenin et al!", I think they are ironically engaging in the very essence of what lead to these attempted revolutions going so poorly. Social and economic rigidity and dogmatism is the issue. Socialism has some good ideas, and can be hellishly bad. Capitalism has some good ideas, and can be hellishly bad. Same for anarchism, veganism, hedonism, and so on. This isn't to say that all ideologies are equal, but that dogmatism is generally very dangerous.
