There's this notion that being able to stream professional theater shows will hurt the industry, because people won't go to the effort to support live theater anymore, and this is based on the anxieties of the film industry, but live theater isn't a film. The better analogy is sports.
Look me dead in the eye and tell me that people being able to sit at home and watch The Game -- the fandom that encourages, the ongoing investment over the years, the memories and traditions of Watching the Game with family and friends -- harms the ticket sales of real live go-to-the-stadium sports. Of course it doesn't. Of course all that *is the reason* that people care so much about sports they'll invest a small fortune on not only tickets but often travel costs to be part of it all in person. And the people who aren't doing that *can't* do that and weren't going to regardless, but their at-home participation and investment still boosts the profile of pro and NCAA sports as cultural institutions.
Maybe it's possible to fall in love with film and be immune to the romance of Going to the Cinema such that you'll just freely choose the same film in the comfort of your living room. It's not possible to fall in love with something that happens live and not want to be there to experience it. The consequences of procasts, for theater just like for sports, can only be A) more people motivated to make live theater part of their worlds, aka more money, when theaters everywhere could desperately use more money, or B) more love. Which is worth arguing for because reasons I assume I don't have to defend.
