Money gives you a claim on labor, so what it does is, it gives you the privilege to command others around and order them to do and make stuff for you. I'd like stability for my family and friends, but I'd find that unethical (beyond a certain point). So I would try to use that power for political purposes funding comrades. Basically what Engels did. He supported not just Marx but also the communist underground in London at the time. I'll never live a live of luxury, because I don't want to. I'd just give it away to help friends and to fund class struggle.
About exploitation and celebrities: if celebrities were to put all their content out for free and relied only on generous gifts of their fans, than I guess in theory, they could get rich without exploitation. But even then, given the state of the world, they would still have more and more responsibility to try and change it the more privilege (money, fame, influence, etc.) they have. In practice, the people who make the merch, set up the shows, handle distribution and all that behind the scenes stuff are the ones who produce most of the value.
I love them, but almost never cook with them, because they are slightly more effort than other carbs.
