Not quite the same thing, but there are certainly places where people will choose to live, without conventional fire department coverage. I live on an island on Canada's coast, where there is a fire department, funded as a local improvement area. It covers ~ 90% of the population, on a much smaller proportion of the island's area. People do live in some of these less-accessible part of the island, but it's outside of the department's service area. Fires in other areas are officially the responsibility of the regional fire service, like for forest fires. Our department might go on certain calls, especially life safety, but will typically keep some people and vehicles back in our own service area in case calls come in there as well. I think the term for people outside of the district is "self-insured", because nobody else will be able to assist quickly.
