What's the story with pedestrianization and gentrification?

Not saying gentrification is a reason to not pedestrianize, but saying it's a risk unless and until we pedestrianize a lot more streets.

I think all these pedestrianization projects should be accompanied by senior housing, so old people who can't safely drive anymore don't spend their final years under house arrest; and they're also extending their lives by walking.

My grandmother used to walk all over her city to do all her shopping, visit friends, go to the cinema, etc. When she came into move with us, in our surburban home, she quickly deteriorated.
