I can imagine a society built on mutual aid, and I practice that everywhere I can. But I have access to tools today. I can vote, I can use my voice to influence the government. What's my alternative, given the reality of today? Convert everyone asking the Colorado river to council communists before the river dries up?
My tool box isn't perfect, but it has some good tools in it. Many of them I'd ideally get rid of and replace, but I'm not going to ignore the tools I have until I replace them with better ones.
