I don't think this is a thing that government can solve. The technology is world wide now, passing a law doesn't stop it. If you can hire an amazing acrobat from anywhere in the world and morph any actor from anywhere in the world as input, nothing stops you.
I do think that there's some kind of "celebrity brain" in people that does want to be a part of a fan base, whether it's a musician or an actor there's a part of us that likes watching other people, and celebrities are very good at being those "other people" professionally. That's never going away.
Acting is a real skill! It's not standing around being yourself and getting paid for nothing. Being a celebrity is not acting.
So maybe if there is some upside to all this, it's that actors may come up ahead of celebrities... the manufacturing of a top 10 list of celebrities in a cut throat competition is probably more "efficient" than funding 1000 community theaters to generate a bunch of actual actors. I'm not optimistic about this strike ending in favor of the celebrities, they're expensive and annoying and possibly un-necessary? That's not a good bargaining position. But actors might have a chance.
Better to pass a law to make it illegal or opt in worst case.
