If you mean bartering, then what people which has been pushed out by AI into uselessness are going to barter?

Not really. "Money" is actually just a middleman that facilitates bartering in new configurations, such as the exchange of goods/services with very different valuations. So there concept is retained.

I mean systems in which there're no expectations of giving something in return for getting something of economic value. That which happens naturally within family.
