Earlier quoted context omitted.
Yes, I am comfortable with the state legislature making law like this because that reflects the will of the people of the entire state. It's only when locals decide they can segregate their streets that I'm annoyed because they violate the social contract we agreed upon. I'm also super comfortable with closing roads to cars entirely.
Fixing the issue with blunt closures in order to close off neighborhoods is frequently bad for everyone: it increases load at the remaining ingress. The neighborhood gets saved the through traffic, but congestion is increased outside of it. Is that something you think is actually preferable to simply avoiding sending large amounts of through traffic on roads which were not designed nor are able to handle the traffic?…
I'm more comfortable with solutions that are even. If you want to install metering lights so be it. All will be equal under the law.
