Because now, anyone can do it to anyone with zero effort and a single photo.

Sure, before anyone with decent Photoshop skills could put together a halfway decently convincing fake nude but its still significantly more effort and time than most would be bothered with and even then its fairly easy to spot and dispute a fake.
