I agree that those are sane approaches. I do think that there can be immediate unintended consequences. If someone didn't pay for a meal, there's propably less chance of a second date. Etc.
I imagine women went through similar consequences while entering traditionally masculine jobs and behavior.
What I'm getting at is that I think that we often think that this pressure is all in our minds, and to some extent that's true, but there are many stories of men opening up and being vulnerable and then their partners lose attraction. That's a hard sell to young men. "Yes, you will be alone forever, but it's necessary because in a couple of generations from now things might be better."
