For example, many people have either a cable TV or online streaming subscription that's another $50-100/month. HBO would be another $15 or so. And so forth.
There is an argument that, at some point, there are only so many hours in the day and a Spotify for video (i.e. most content for one monthly fee) makes sense but that's probably a $100-200/month fee in the US (assuming you could get most players to cooperate). YouTube TV alone is $65/month these days.
