Sure. Which is why, in addition to telling people to wear seat belts, we also make people take Driver's Ed so that they can demonstrate that they at least nominally know the rules of the road and can drive safely.
What's the Driver's Ed version of teaching people not to commit rape or sexual assault? When I was in college, there was a freshman orientation activity that talked about consent, but it wasn't mandatory, not all colleges have it, and not all people go to college. Who's teaching high schoolers about the nuances of consent and what it means to sexually assault somebody?
Do you tell banks that they shouldn't have kept so much money in the vaults if they didn't want to get robbed?
Well, it becomes a meme of some sort, with everybody making fun of the bank. For example: there is over a million dollars in cash, the bank is near multiple good escape routes, the bank's cameras and alarms are broken, the "vault" has a hollow interior door, etc.
Why not? When two people don't have the presumption of consent, what's the harm in checking to make sure "hey, is this something you want to do?"
