I have a feeling that it would be more along the lines of the patron-client model that propped up the creative economy of Renaissance-era Italian city states. The key difference being that, with basic needs met, you'll no longer have to bear the last name Medici to have the resources needed to become a patron.
On the other hand, I also think that, in light of the climate crisis, we may have to significantly scale back the commodity economy. One way I envision this playing out is a reservation system for raw material on a community basis that would enable a grassroots patron-client and gifting ecosystem.
[pls note I have no sources to back these theories up. They're a hodge-podge of stuff I've come across over the years]
That is one part of the equation, sure. Buy It For Life should be a cornerstone of transition economies, at least. However, I feel like future policymakers will have to be more radical and find ways to shelve commodification as a mindset altogether. This includes the concept of "shopping" as a leisure activity, but also other things such as consuming entertainment at the volumes we do today, and reduction in the role of consumption in courtships. I'm not even sure if such a shift is possible, and would possibly cause widespread resentment if it were to be implemented at scale.
