"Unlimited" is a difficult claim to justify, but as evidence that human wants are in vast supply you might look at the way that Buddhism and Hinduism portray the bulk of human society as trapped in an endless cycle of wanting the next thing. It's not impossible to escape, but expecting it to happen en masse might be a stretch.

I think a more fruitful direction would be to distinguish between empty dopamine, and the kind of want that you can look back on and feel like it was aligned with your broader interests.
