I mean if you live in a city like Paris, then yeah I'd say that's legitimate. I see nothing wrong with making such dense urban centers car-free other than what's necessary like deliveries or ambulances and such, but for the former these days you've got tiny electric trucks that even fit on bike paths without causing a ruckus, usually you'll see those grocery delivery services use them.

Yes, people outside of urban cities like that (which, basically by definition means the majority of people in the country) still need cars to get around most likely, but at least we can ensure that inside the cities themselves, there are good alternatives for people to get around that benefits every single person who finds themselves in the city not inside a car, which will be the overwhelming majority of people.

I live in Utrecht in the Netherlands, and the single best thing the gov't did a few years ago is rip out the highway that was in the city center and instead turned it back into a canal surrounded by parks [1]. Literally nobody who has ever been to Utrecht would argue we were better off with the highway.
