"everytime I see someone famous stopped by a fan I kind of shudder and consider it a cruel invasion of their privacy and definitely not something that comes with the territory."
I'm sure they appreciate being stopped by fans and told that someone actually does like their work. And while it's been debated, the inflated salary costs of big name stars is b/c they have to deal with a certain amount of publicity.

Everyone has their collectibles, whether it's the playbills or baseball cards or autographs.
You gave the example yourself of some celebs who do shows where people pay for their autograph. It's a business for some whether you're collecting or selling.
If you really want to help the American theater, don't be an actress, dahling. Be an audience.....
Don't be taken in by the guff that critics are killing the theater. Commonly they sin on the side of enthusiasm. Too often they give their blessing to trash...
