Please expand on what you mean.

For context, I live in greater Boston. The state here has actually forced towns and cities in the inner belt around Boston to remove their zoning laws anywhere within a mile of a train or subway stop. Thousands of additional condos and apartments have been (and are being) built as a side effect and we will have dozens of new squares with shops and businesses on the ground floor surrounding our transit hubs.

It’s not been smooth. Some towns are suing the state and doing other random bullshit to slow the process. Pushing these rules to the federal level would actually help states and metro areas consisting of multiple connected cities address the issues more efficiently.
