Generally a enterprise that is not profitable is using more resources than the value it creates and as a result the economy is better off if it goes under.

This isn't just "things only deserve to exist if it makes someone money" this is "our system systemically discourages wasteful use of resources".

Actors and such need to be paid. Their labor is a scare resource so if they are doing something that's not worth more than their time, they should generally be doing something else. If we all behaved otherwise society would slowly die as wealth got consumed to zero instead of increased with time.
