I'd far rather see racks and racks of artificial uteri than dormitories full of women incubating babies for others. In fact, if the technology works, I wouldn't have a problem with people opting for this rather than going through pregnancy, which has it's own risks to women's health.
But I also think technology like this would embolden anti-choice campaigners. That would, I think, be very bad for women as women's decisions to abort are rarely driven by concerns for the impact of pregnancy on their bodies.
