This, to me, is a good illustration of one of the many flaws in the 'let the virus rip' idea. Cinemas are open and have been for a few months. Despite this, they haven't been able to reach anything approaching (socially distanced) capacity. https://www.theguardian.com/business/2020/oct/04/cineworld-to-close-all-its-uk-cinemas-putting-5500-jobs-at-risk
Unlike many other industries, I think it's hard to argue that people aren't going because the experience is dramatically changed by the public health regulations. People don't want to go to the cinema during a pandemic.
Surely this would only be worse in a situation where incidence was much higher because we weren't trying to prevent transmission? There are so many industries that were always going to be decimated - it's part of the reason why a respiratory pandemic is such a catastrophe.
It's vital to consider the health impact of this economic collapse, of course. However, what we need are interventions to mitigate this impact - pretending that everything would be fine if we went back to normal doesn't help anyone.
