If that is true, then a thought experiment would be: should refusing to enter prostitution be a grounds for losing jobseekers' welfare, eg. jobseekers allowance [1]?

I agree with the general principle that not all labour is the same, but I don't think prostitution is in a class of its own. If you paid me enough I'd probably do it for a week and then retire.
Maybe this means that you don't really like your job? If you had access to the same goods as everyone else around you, more or less, and liked what you are doing, then doing it for a week stops making sense, doesn't it?
