Nude pictures are fun. For all the reasons it's fun to take pictures at all, plus love and sex.
In a relationship that isn't really obviously screwed up, you have basic trust for the other person.
Part of that trust ought to include encryption, but that's another story.
I think that this situation is atypical. Leaked or lost personal photos might be available to the whole world, but most don't go viral linked to your name. So the 'normal' risk of a douchebag boyfriend is relatively low.
And why is it a risk at all? Why isn't it just safe and fun? What's the harm? Take this passage:
>My professional reputation? Tainted. My parents’ perception of me as their angelic baby girl? Blown to smithereens and then reassembled in the likeness of a leper.
>I sobbed daily.
Where is the harm here? It is coming from her potential employees, colleagues, and sadly her parents. They're the ones with screwed up attitudes about sex. It's their fault, not her fault, because she did nothing wrong. I hope their views are not as harsh as she thinks. But even if she's imagining it those are the ideas we get from our culture.
I get that you're worried about it coming out wrong, but much of your post was similarly victim blaming. The actual solution to murderers in alleys is to send police into the alleys. Not restructure our lives to be tolerant of the constant risk of murder. We should not just cede power to evil because the alley is dark.
And this is not a physical attack, all the harm is in the views others take of the victim. Your judgement of her judgement is part of the harm that the attacker expected.
A betrayal of trust should be blamed on the betrayer, not the betrayed. Is there room for learning better who to trust? Sure. Should we expect people to act like they can't trust anyone they love, and add scorn because they were the ones who encountered trust-evoking douchebags? No.
Personal porn should be fun and safe and relatively inconsequential, for all the reasons that love and sex and photos are fun.
