The question you have to ask is whether or not a "booth babe" would choose such work over others if they had a choice and not merely because it pays the bills.
Would you choose the job you currently have if you had another choice and not merely because it pays the bills?
The arguments against capitalism and against sex workers are two completely orthogonal things. Sex work is a consequence of capitalism + enforced class systems perpetuated by leadership.
Fix those things instead of claiming women who have complete personal agency in what they do with their bodies are still being exploited. Of course they are. All of us are being exploited.
Being a booth babe is an option not open to unattractive people. Seems like a superset.
