As long as the risks are made clear to the women involved, then I don't see this any different to a nose job or any other type of cosmetic surgery.
There are women out there who have misshapen or uneven labia (not me, in case you're thinking it) and might want to neaten it all up. Or they may simply want smaller ones like they might want larger breasts.
I don't really care if someone wants to pay to make something they consider ugly, more attractive by their own standards. As long as they are psychologically healthy then they should be able to do what they want.
