I have similar feelings.

I am sympathetic to a perspective that says this is not the responsibility of a mayor of a single city... But also; who else is going to do it?

Normal people have very little say over the politicians that govern them in larger electoral regions like states or provinces, and maybe this can signal to other levels of government that they should implement similar rules... If it works.

CFPB once played that role for financial services. Ah well.

With a population of 8.5 million if NYC was a state it would be the 13th largest so I'm quite all right with the city going beyond the normal purview of a city government.

Mamdani has been doing great in NYC so far. The hope is that he will inspire similar behavior in others. And drive similar approaches to politics in other constituencies.
