My experience from watching lockpicking lawyer is that locks are just social niceties that tell others ‘please don’t go here’ and have no real ability to stop anyone who doesn’t care. Other than the owner who gets locked out by forgetting their own key of course.
I think it’s fair to say they’re are some significant similarities between the two industries. They both focus on large, multi year creative projects with unknown returns. I’m not sure emulating Hollywood is the answer, but they can at least look at how existing Hollywood unions have approached addressing any similar problems
