I find it incredibly interesting from a Swedish perspective that in the US the left and right position on this is reversed compared to Sweden. Over here the left would decry you as the worst sort of neoliberal who sees women's bodies as trading goods if you supported legalizing this. Heck large part of the left doesn't even want to allow surrogate mothers, because it is rich couples "buying" poor women's wombs.
The difference, as far as I can tell, is that unlike the Swedish left, which is primarily focused on what is best for society at large, the American left is focused on what is best for the individual and their own selfish desires. There are people who want access to prostitutes and religious folks are outraged at the idea; it's a win-win for the left.
