Memes of Production

I'm not sure I agree with this analysis. It's certainly true that mutual aid is a natural instinct that causes people to support their direct social network. But it does not always lead them to help more distantly connected people as substantially. At the scale of a whole society or world this could be a problem. The key of a successful socialism would be designing an economy where people are sufficiently motived to produce and share enough to support a prosperous society. I don't think this is impossible but I also don't think it will be automatic either. It may require careful thought and experimentation about how those incentives will arise and be cultivated in the new economic system. Ideally they should be cultivated with minimal coercion, lest the new economy be hardly better than the old one.

If people would come around on degrowth it would probably be a lot easier. A lot of our labor currently goes into trash that doesn't meaningfully improve people's lives, so doing less of that will require a lot less labor and therefore motivation.
