> So how come there are countries without a natural monopoly and with competing utility providers?

Local governments own most U.S. utility lines and pipes, so a competing for-profit utility would have to go against the not-for-profit public service, leaving low to no room for profit and no reason to even compete.

Fiber/cable/dsl lines are one of the few U.S. utilities with competition because the performance/reliability/features of the service can vary greatly and because almost no local governments ran their own ISP before private companies came in and ran their lines. I can bet that any area with a municipal ISP has a very low chance of seeing xfinity/att run their own fiber if they're not already servicing the area.
