How to enrage the proletariat

Donations don't have anything to do with socialism. In fact many porkies advocate that instead of social programs we should just use charity to lessen inequality.

If there was universal basic income, would Belle have to do this for money?

If she did this as a hobby and there was demand for it, can others not pay her?

I'm not complaining about what she does and would gladly throw money at her if she did it just as a hobby.
All I'm saying is that this isn't socialistic in any way.
