Personally, I think if the only way you can have a harem of busty broads is to literally buy slaves you’re a pretty pathetic fantasy hero.
Free the slaves and have a harem of slave owners
I just searched for woke SJW and feminist, my god the comments are awful.
Why look for those comments? They have literally nothing of value to offer, rather the opposite, the incel/“anti-SJW” crowd all deserves the wall. In their “wholesome slavery fantasies” all the cherry boys and basement dwellers would absolutely join the ranks of the slaves (or simply be killed off for being annoying, useless eyesores) for that matter.
Isekai authors are not good enough to do a setting with slavery that’s not disgusting, so they shouldn’t.
I argue that their lack of skill is what attracts them to the genre in the first place. Don’t have to do too much setup if you can just plop your hero in some random setting.
