But, many do due to the lack of alternatives. Especially in the US/Canada, but also in Europe (especially anything built recently). People will drive because they don’t feel safe cycling/walking, or because their destination is too far. Or they will own several cars while they could just go on with one.

I don’t think anyone is really advocating for completely removing cars from the street or cities. I personally don’t own one (and this is a priority for me - I don’t want one), but I do take rides with friends or a cab from time to time.

What most advocates want (including me) is to stop prioritising cars in every single decision. Mixed zoning laws will remove lots of car trips if you can just walk to the shop when you need a couple of items or a coffee. Making streets car free (bar few exception) will make people come out and enjoy the street. Making people pay a fair price for parking will avoid subsidising a huge amount of land for private use. Removing parking will add lots of space on the streets for things that people enjoy. Better public transportation will favour everyone, especially poorer communities. And proper ciclying and walking infrastructure will allow more and more people to do so safely.

If after that someone still want to use private cars, then be my guest.
