>Why is the answer to anything related to women's bodies always to propose controlling what women do with their bodies? If men could rent out their reproductive organs, nobody would say anything about it and there would be very few laws.

Because it affects all of them, not only the surrogate. It's like pornography. The women that criticize it argue that it exploits and incentivizes the hypersexualization and objectification of women. While not agreeing with their requests, I don't think they are necessarily wrong.
