If you actually had to pay a proper price for your parking space, which is currently heavily subsidized, you would suddenly consider taking public transit instead, even if that were priced at actual cost.
Consider that the "one size fits all" approach into forcing people out of cars breaks down very rapidly once you get out of sight of the sickly LED glow of streetlights.
Suburbs are _cheaper_ than dense cities. In fact, they generate most of the wealth of the country. It's easily proven by checking the amount of personal income taxes from suburbs versus cities.
People who claim that "suburbs are subsidized" typically check the _corporate_ taxes that are paid (surprise!) usually at their headquarters' locations. Usually in downtowns. But _people_ who create wealth overwhelmingly prefer suburbs.
And yeah, if your goal is to maximize the profit that you're extracting from companies by exploiting people, then dense cities are perfect.
