Why not? They can make you wear your seat-belt, hang up on the phone and deny access to the toilet even if you are wetting your pants.
It would not take much to enact a rule about wearing masks, if that's what the industry demands. Peer pressure from other passengers (like the big guy next to you who smacks you in the ear) would take care of any recalcitrant.
As inconvenient and ineffectual as it may be (just like the farce that passes for security), if masks are required we will have little choice but to comply.
