Most theatres are not at all scared of MoviePass, they're getting paid the full admission price. In fact many chains and independent operators love it, and are looking at implementing their own version.

Not really, no. Studios are the ones driving up movie prices since they keep demanding a bigger and bigger cut. The new Star Wars film for example has the highest royalty of any movie ever released.
