Edit: I'm curious if people are downvoting this because they're anti-trans, or because they think I'm somehow anti-trans.
Essentially, it's likely possible, but even womb transplantation into women is highly experimental and may prove to be unsafe, without the added limitations of male anatomy and hormones.
I wonder about the placenta and umbilical cord though.
A: implant womb in person, implant fertile egg in womb, carry baby, c-section deliver baby, remove womb.
B: implant fertile egg in surrogate, carry baby, c-section or give birth to baby.
Or: it's just surrogacy with extra steps.
Adoption has its own place in the world but everything which allows women to give birth (especially in the West, where this is starting to be a problem) should be ok from this perspective. If you want to talk about wasted medical resources, just take a look at the plastic surgery market.
You seem to be unaware of how difficult it is to adopt children in most countries: it's years of paperwork and bureaucracy and you never know if and when it's going to work.
Do not underestimate effort adoptive families, kids and parents, do.
