I don’t think that everyone will stop working just because they can. Even if everything even non essential goods would be provided for everyone, we would still produce luxury good, arts and services. So it would in the best case evolve into something like market socialism where everyone profits of of the chance to never have to work again. In the worst case we would be stuck with a system where few hold these unlimited resources and make people work by holding back essential goods despite being abled to provide for everyone. In both situations I think money would probably still play a role.
