People 'exempt' from paying are those with a concessionary pass, so something similar should be in place for those exempt from wearing a face covering.

I do agree that it's impossible to enforce, but not even having the illusion of enforcement is where the issue lies. If they don't challenge anyone, people are going to continue to avoid wearing them. If they ask you every time you board without wearing one, then soon enough you're going to get sick (hopefully not literally) and just start wearing one.
