not to open a can of worms right before i fuck off to the cinema with my head chef, but if you think prostitution should be 100% legalised and should be a job just like any other where you exchange your labour/skills for money then the logical extension is that if you are unwilling to do “sex work” while claiming unemployment benefits you would be cut off for refusing “reasonable” employment
this already happened in germany, perfectly legally. though the general consensus among job centers is that women should not have their benefits cut if they turn down prostitution jobs, it’s completely legal to do so
