Yes. You need to have at least twice as many firestations to have a choice, if you want to choose between fire services, though.
You’re gonna sit there on your phone trying to decide which fire service to use while your house is literally burning down?
What about people who rent? It’s not their own private property, are they supposed to pay for the whole building being saved? Does it get put on the landlord? He never consented to having his building saved, his tenants just called the fire station when a fire started. Are the tenants supposed to contact their landlord first so that he can properly consent to having a fire station save his property?
I don’t see a problem with having twice as many firestations, as in two parallel services. They don’t have only one landline at the firestation after all. They have HA in any mass service system.
Well other than now having to pay for double the amount of infrastructure, you now also probably have people who own and profit off the stations, which introduces every normal market pressure, positive and corrupting.
Notice how it requires no coercion
“Pay our massive fee or your house burns down” certainly sounds coercive. You’ve also not established anything to guarantee that a fire station doesn’t develop a monopoly.
See my solution.
If your solution to serious and urgent emergencies like “Oh my god, my house is on fire” or “Oh my god, I’m having a heart attack” is several paragraphs long, you’ve not actually developed a solution, just a hypothetical which shows painfully obviously why we stopped running society like this millenia ago.
