Propane's a different thing. It's just trading in bottles. Those bottles will keep being available for a long time and are, frankly, not a major emissions source. Still one we should get rid of, but it's not a low-hanging fruit. Propane is also still one of the more climate-friendly refrigerants, so it's definitely sticking around.
As far as people in situations like that relying on fossil gas distribution infrastructure... one way or another they're going to be left holding the bag.
Electrified appliances are almost universally better for consumers both in quality and economics. Electrification and gas-free new construction will keep happening. Keep accelerating.
The infrastructure of gas is already built. It costs a lot to maintain it even as poorly as they do. As fewer ratepayers are using the system, the remaining ratepayers have to pay a larger and larger share of that cost -- making the gas even more expensive and an even worse choice for consumers. Inevitably, the poorest folks who cannot afford to replace their appliances but also cannot afford to keep using gas will be left behind. That's the reality of the privatized system we have.
I feel bad for all the people who are going to get fucked, especially since for many it was bogus that they were saddled with fossil gas in the first place (e.g., bribes to builders/subdevelopment managers).
