There are other reasons not to want to. I like being self-sufficient. I like knowing that I could keep myself and those around me more safe if there was a threat. Etc. My environment would probably be fine with me if I did not want those things-- or at least I've never considered whether they would, because it's not repercussions that make me want to be me.
I think the difference between "I can't" and "I don't wanna" is big enough to be worth splitting. For instance, when trying to think of reasons for men that "can't" abandon masculinity, you're looking for externalities (pressure). If you think about why don't men "want to", you'll find plenty of self-serving reasons and rationalization, which in my opinion is a more realistic framing.
