ELI5: Why do we have to pay for cable/satellite/fiber optic TV each month, when all the shows still present ads?

The bill you pay every month is for the infrastructure to deliver the cable single to your house.

The commercials are to pay for the actual programs that you watch.

It's like asking why you have to pay for a train ticket just to visit another city when you just have to pay for all the stuff you do in that city.
