I would not enjoy that, but other people don't exist to make me happy. If Paramount owns the movie theater, they can show whatever they like. If I don't like it, I can start my own theater, watch movies online (I realize this wasn't possible in the past, but the Internet does help free markets tremendously), organize a boycott of Paramount, or try to get another theater started some way.
It was proven that those things didn't work. (Or do you think no one thought to try them?) So you can't say "I would..." as if you're the only smart person in the world that those things could possibly have occurred to.
That was the situation that actually happened, this is not a hypothetical you can will away by some kind of magic. It's a true story.
The only choices were government intervention or letting the corporation control your choices by way of localized monopolies.
You have to pick one of those things. There's no magical middle ground where you get to pretend you get everything you want. The real world doesn't work that way.
