You're going hard on that by your logic thing aren't you? I think communism is effective at opposing capitalism due to its ability to resist capitalist imperialism and even fight back, this is not a belief that what lasts is good. We've gone far from the asinine point you were trying to make that communists just theorize btw, you moved on pretty quick from that to 'actually left projects being capable is bad because capitalism can be capable too'

By lasting at all.
