Wrong.

Sports teams are localized to one city. Do the Beatles only play concerts in one city? Nope, they traveled the world. Do you pay taxes in your support for the Beatles? My city just recently built a badass new stadium in Indianapolis that WE had to pay for. Are there Beatles merchandise shops anywhere? Probably not; I know of at least 3 stores where they sell nothing but Colts merchandise in Indianapolis.

Your analogy is terrible.

If there weren't fans that came to each and every home game, there would be no football team. That's a fact.
