Personally, I don't see why we shouldn't have the same right to make bad decisions as cis people. (I know one woman who will tell you she waited 19 years for GRS... and regrets it. If "no one regrets it, ever" is the standard, the wait time would be infinite; if it's to prevent *some* regretters, I'd like to see actual evidence from solid studies establishing where the line should be drawn.)
With that said, there actually are plenty of paternalistic doctors who also won't hand out sterilization to cis women on demand, and tell them they'll change their minds. I'm not saying that's a GOOD thing, but it happens.
