We should accept that there's both people for whom sex work is just like any other job, and people for whom it implies renouncing to an element of privacy they'd rather to share only with their partner/s. Should it be legalized? By criminalizing it you're screwing over a lot of people who do want to perform that work and don't provoke any issues in the world, but legalizing it might have ramifications that are horrendous.

For instance, say your country has an unemployment system where you'd lose your unemployment benefits if you receive a job offer and reject it, and immediately after getting fired you receive an offer to work at a brothel. That's great if, for you, there's no emotional element attached to sex, but for a lot of people that would be a nightmare, especially if they need either a job or the unemployment benefits.

So, my take: decriminalize sex work but don't regulate it yet. Once we have either socialism or UBI or both, and no one gets under risk of suffering personal misery for not having a job for a while, legalize it like all other jobs.
