I feel optimistic we're getting closer to resolution!

Funnily enough I get the opposite impression. Please enlighten me with those lots of exceptions which I fail to find. Just to be precise, Mannish spirits remaining in Middle-earth besides Ringwraiths and Oathbreakers and frodo's Morgul wound. I guess three cases is not much to keep apart because you have lots.
Well, if you count the thousands of Erech ghosts that's
lots. (Or none at all.) But there's also:
- Barrow wights
- The broader implications of the Morgul-knife story
- The ghost lights of the Dead Marshes
- Beren's willingness to believe that the wraith of Gorlim could come to him a dream
I know you have alternative explanations for each of those, but that's the thing...it requires alternative explanations. The point I'm making is that all these cases stack up against one sentence, about the gift being mandatory, and it seems simpler to say "Involuntary, but not impossible" than to create convoluted arguments for all the counter-evidence.

There is no evidence they could or did. In fact when Sauron made them regret been mortal, instigating the rebellion against the Valar, it was because they could not resist the gift. Otherwise the rebellion would have been pointless.
Well Sauron would hardly have been dumb enough to
actually teach them the secrets, secrets he obviously knew, as evidenced by the Ringwraiths. Would have kind of spoiled the whole point of his plot.

Problem abusing that is that it becomes no exception but a loose rule, and every major event that happens becomes a chain of events instigated by Eru which is supposed not to meddle save in very few occasions.
If used sparingly, it's only a problem if the underlying motivation is an aesthetic dislike of Mannish undead. If we're talking scholarship and canonicity, there's no problem. (For the record, I find it unlikely Eru would have personally interceded in the Erech case, as well, so I'm only using your argument here.)
