Can you give reasons why it wouldn't besides people (which includes payers) don't want to use it?

Sure! Acquiring the required paperwork and banking connections to get on crypto on/off ramps is difficult. That's one reason.

Anyway, see how you retreated your argument to "which includes payers"? So it seems that you actually agree with me that artists wouldn't be able to set up crypto payments to provide a livelihood for themselves, due to reasons which are outside their control.
