Actually you are correct it's not Zero. It's negative. If your claim were true, no one would clean the crapware off their windows machines. With respect to tv channels extra channels impose poorer usability for the on screen guides, and degrade a simple channel surfing experience.
(Note I'm not claiming the bundling prevents purchase, just that there is an economic opportunity in non-bundled alternatives, such as Windows boxes without crapware, or solving the problem of a clogged experience due to poor bundling such as Netflix's focus on surfacing desirable content.)
An extreme example and still totally unconvincing. I don't speak Spanish but would like to learn. My wife's family doesn't speak spanish but their nanny does. My brother doesn't speak Spanish but watches futbol. My dad likes to stop on telemundo periodically. My other sister has a few Spanish speaking friends. And on and on.
Everyone has their own utility and I guess we just differ on ours. I don't want to generalize but I personally wouldn't pay more to have a set of Spanish channels. Arguably if there were too many Spanish channels I'd pay less since navigating my TV would be too difficult.
