How does that disprove him?
It seems like idealism to somehow want to say that prostitution is not work simply because it gives pleasure
Like is an ice cream taste tester also not a real job??
Sure all jobs are not real under capitalism, most jobs now are consumer based that aren't actually creating anything productive
All workers are exploited, some use tools, some use PCs, some use their bodies and some have sex with other people
Why are we wasting time creating this bullshit lines amongst workers exactly?
