The surrogacy industry and the sex trade already have a bunch of wealthy men from first-world countries eyeing poor women in third-world countries as raw materials for their vanity projects. The Tranch boys have no empathy or regard for others, so they absolutely wouldn't care about the economically desperate women they hurt (or kill, since death is a risk of all major surgeries and pregnancies). Bonnie doesn't even care about his own father dying - he just wants a shiny new truck. I'm sure that sentiment would carry over to some shiny new organs or a shiny new baby. Luckily these horror-scenarios are purely hypothetical, since Kevin is a lazy shut-in who Tweets all day, is broke, and can barely walk, so he won't be able to fly to India to rent a person's body or con an organ donor.
