"Suburbanites shouldn't have to pay for city subway and potholes."
Then city residents shouldn't have to pay for the roads that make car-centric suburbs possible or the various subsidies given to rural residents. Honestly, one of the benefits of civilization is that we help each other out even when it does not immediately benefit us as individuals. Rural and suburban life would not be possible without cities, and cities would not be possible without rural and suburban residents.
Cities form naturally because of industrial operations that are more efficient when they are concentrated in a single place. Remote work changes nothing about it because there are still plenty of jobs that cannot be done remotely, including many of the jobs needed to support remote work (e.g. data centers, warehouses, intermodal terminals). Suburban life depends on industries that make no sense in suburbs or whose presence will ultimately transform suburbs into cities.
If suburbs were as superior as you suggest, cities would not be growing and real estate in cities would not be as valuable as it currently is. People are choosing to live, work, and raise families in cities more than they are choosing suburbs. Remote work has not changed anything and will never change anything. COVID-19 led only to a transient spike in demand for suburban homes that is already declining as people realize that the pandemic is already in its final stage.
Migration patterns overwhelmingly demonstrate that people are migrating from high density cities to low density, "hardcore suburban" cities. In the US, high density living is a boutique lifestyle choice that is constrained in the offer side (NIMBY), thus the prices. The fact that there are people willing to pay for this lifestyle doesn't mean that they are a majority, or even a significant percentage of the overall population.
