The medications and treatments often prescribed for trans people typically have other uses, so unfortunately for those who want to ban trans care, it's not possible to ban the treatments entirely, just come up with policies for being really selective about it. Those policies will not be terribly fair or effective.
Otherwise you're denying other people access to the same care even though you might believe they need it - reconstructive plastic surgery for cancer survivors, androgen or estrogen suppressors for people with various hormone regulation problems, hormone replacement for post-menopausal women or men who no longer have functioning gonads, etc.
Incidentally the latter is why Californian insurance typically covers surgeries for trans people: They already cover the same surgeries for other cases.
