No, you have made up the "purpose" in your head. You frankly sound like a dumbass repeating it so much.
I have never said anyone has a moral obligation to buy ESPN. Never. Not once. Go look at all the thread, and show me where I said that. You can't, because I never said it.
Now getting to your point, some people don't want all that content. That's fine. However, what you don't realize are the ramifications of this. Some content that you DO WANT isn't going to survive this, at least not if it works out the way you imagine it.
I don't know what you like to watch. Let's just say you like watching the History Channel. Ok, well the History Channel simply can't survive, not even with a skinny bundle. What you don't understand is, there is floor for production costs. There is simply certain cost that has to be met for a given channel to produce content and stay in broadcast. If they don't meet that certain cost, they simply have to go out of business.
Now, if EVERYBODY is only paying $20-30 a month for TV, then 75% of the channels are gone. If that doesn't bother you, that's fine. However, what will most likely happen is that the streaming providers will do what the cable companies did: they will start expanding packages (and raising the price) to include more content. Not all of the streaming services will survive either. Some will not make it, the market will be consolidated, and those remaining will be able to price things higher. Like I told you, there's no such thing as a free lunch.
