Lots of places are looking into phasing out natural gas though. California gives you rebates for heat pump water heaters and there's plenty of discouragement to block new gas appliances and hookups.

There will be a feedback loop once that really starts: individual prices go up because infrastructure costs remain the same. Once natural gas prices go up, people will switch to more efficient appliances, or switch to electricity. Forcing prices to go up some more to make up for infrastructure costs.

At some point running a heatpump will be cheaper than maintaining a natural gas hookup in your house. And that will just make it more expensive for everyone else until they do the same.
