Basically, "small cameras/microphones, cheap enough to be everywhere" completely changes the "free to take photos/video in public" equation - so that's probably worth revisiting legally.

Clearly there is a difference between someone waving a SLR camera around (digital or film) and the possibilities of today and where the content ends up.

However... the pub/bar/nightclub, gym, pool, etc etc etc isn't public. It is the private property of the owner. So if people don't like them - as is evident it seems - these glasses should hit social resistance.

It'd be fun to adapt copyright law to cover people's physical form. Imagine a huge class action suit against Meta for enabling such copyright infingement.
