There is not much urbanized part of the metro to speak of. It’s all suburbia, even in the city itself, 75% is zoned for single family houses. Given that my property taxes are 10 times what Strongtowns thinks it costs to maintain the streets, I seriously doubt I’m being subsidized by anyone when it comes to infrastructure.
A lot of people assume that urbanized metros imply a lot of high-rise residential. But take a place like Somerville in MA. It's one of densest cities in the country outside of the environs of NYC and there's not much high rise construction generally and a lot of the city is standalone houses.
What about the fact there are two of the largest tech companies in the world headquartered nearby? The downtown most definitely subsidizes suburbia.
Microsoft practically built a whole suburban town far from Seattle and made it its headquarters. It subsidizes suburbia because it is suburbia.

That said, I agree that total collapse of municipal finances is unlikely outside of particularly poor exurban areas.
