Something that was previously unaffordable becomes affordable, people will naturally seek it out.

Be that as it may, just because something like a sex change becomes cheaper it doesn't mean that most people start considering it all of a sudden. Don't discount the stellar work "experts" are putting in, convincing all those people who just didn't know what they were, especially teens. I remember reading that gender dysphoria was fixable by less invasive means such a medication.
