Part of the problem is that, frankly, even the countries that are friendliest to sex workers are ultimately rife with exploitation. When it comes to the perceived value of sex work, the gap between what providers believe and what consumers believe is very, very wide, and those services are so "fundamental" that I don't think they're really subject to market forces in the way other "luxuries" are.
So while I'd love to see a world where all sex work is consensual, destigmatized, and ethical, I don't think it's possible to really build that world. There will always be huge demand for sex work, and that's a demand that cannot be met by people choosing to become sex workers and offering fair prices for their labor. It will be met either be people being exploited under an unfair capitalist system, or by human trafficking.
Ultimately I agree that it should be destigmatized, and that the women involved should be treated with the utmost respect - that's always something I try to do. But I have trouble with the "sex work is just another job" argument, because that requires you to blind yourself to the fact that a vast, vast majority of it, globally and historically, is exploitative and/or non-consensual
