Cars are a reasonable solution for some situations, and there’s no reason it can’t be a hobby. If we design cities for cars, invest in car infrastructure, and don’t build or invest in other transportation infrastructure, we get what we paid for.

A better perspective is we should design cities so you don’t need a personal car, design cities so a personal car is more expensive and less convenient.

Instead of worrying that people choose personal cars too often, let’s all worry that our cities don’t always offer any other option

Yup, I think passes would work, together with restrictions of where they park, and some system of effective enforcement.

I disagree with the ban of car ownership though. That's just not the way. If you make it convenient enough to use alternatives, most people including the more vulnerable people will adopt it. Most people with families use cars because it's just not practical to take the whole family in the bus. Not to mention people with disabilities that can't use transit (e.g. Chronically I'll or severe autism). Bans would affect these people disproportionately.
