I’m wondering what kinds of idiots would PAY someone to surf.

[Tax-chick]

The same sort who pay people to fish ... that is, manufacturers of products that will be bought by people who like to watch surfing. This includes products immediately associated with the sport, such as surfboards and swimsuits, but also other clothing, beer, food, certain types of vehicles, etc.

Even businesses unassociated with surfing or a "beach lifestyle" could choose to advertise through surfing, if they're near the beach. It's an obvious choice for real estate agencies in the relevant area, for example.

It’s a huge industry and marketing machine. Where have you been? That said, this skank just dropped in for her last ride on the aforementioned.

The same kinds of people that pay other people to play sports.
