I'm going to put my hand up and say I have absolutely no idea how an ISP works. He runs cables to each house in the area... now where does the other end go?

If you just Google then it's usually called leased or dedicated internet
Just some (US) examples

But also because once you're in a single location, you can pretty easily get multiple providers to that location for a Price, so there's really no point. Even small rural towns usually have multiple internet connections from different companies, and if they don't you can pay to run fiber if you really wanted to.
People find it hard to believe, but Comcast et al are actually businesses, not Satan's marketing department; and they happily take money even from "competitors".
Comcast would much rather sell a dedicated fiber to a business with capital and guarantees.
Selling to the individual consumer doesn't make a lot of sense business-wise, because of the deployment costs and continued support costs.
Comcast is also abusing their status as oligopoly to gouge costumers financially and qos-wise, but if they're selling to a business that buys large quantities and has staff who's job it is to handle network problems, they actually like that (right up until that business threatens to compete with them in areas where said oligopoly is in place, of course)
