Elon is so full of shit.

Someone will always have money and power. When someone tells you that you will no longer need money. What them mean is that they will have all the money and power and if you behave yourself you'll get enough to survive.

I don’t know why they think demand will not be able to keep up with supply. If not money then what will the allocation method be for limited goods? I want land. Lots of it too. Even the AI army can’t make enough good land to satisfy everyone who wants good land.
