The library costs you money too, in the form of taxes. At least Netflix only charges its actual users. I'm forced to pay for the two public libraries in my town even though I've never been in them.
Your taxes also maintain roads you never drive on. And yet you still benefit because the trucks that supply your grocery store or the plumber coming to fix your sink might use those roads. That’s the point of taxes: we all pay in, and we all reap the rewards.
