But where are all these surrogate mothers going to come from? Even if payment and commercialisation were legalised (in the UK) I really don't think it's something that large numbers of women will be queuing up to do.
Maybe they plan to force us to do it. Maybe the plan is to guilt trip us into it ("trans people will literally die if a surrogate doesn't come forward you selfish bigot!"). Maybe they've reached the "axolotl tanks" stage of misogynist batshittery.
In the case of this particular young person I don't think the question has even occurred to them. Long term consequences, what are those?
