An excellent question, as a practical manner. Mind, there are ways people can be compelled to pay, within various limits. Some search-and-rescue services (I believe in Norway, for one set of examples) have a nominal, voluntary fee that hikers and skiers can opt to pay or not. If payers need rescue, they don't have to pay anything beyond that original fee. If non-payers get rescued, they get a big bill for search helicopter fuel, labor, etc. spent in looking for them. Something like that seems sensible to me - if the guy had said, "Yes, please put out my house, I'm aware you'll bill me,", maybe signing a waiver or whatever to prevent problems with the firefighters' insurance company, then the firefighters could try to save his house and then the city could bill him, then sue him or garnish his wages, etc. if he refused to pay.
