I don't know. Has this been a waste of political capital? It
seems like this was a non-issue when it was actually passed, so no political capital wasted there. Most of the fighting has been with a faceless state board that determines compliance, so politicians generally don't have to stick their neck out. In a lot of cases, it seems like the people wasting political capital have been NIMBYs. They're the ones who have to waste a lot of time and effort. They've been the ones mostly losing and beating their heads against the wall. And a bunch of NIMBY groups are probably coming out of all this looking worse than they did before. Zoning is suddenly a more popular issue, more people are paying attention, and a lot of reporting I've seen will cover some of the craziest shit said by NIMBY groups.
And I agree this one law won't generate a ton a new housing on it's own. But I'm not sure what one law would. There are
hundreds of regulations holding back housing development. Fixing any one of those regulations would only help a little, because there are so many road blocks. Really fixing this problem is a long-term game of whack-a-mole. I guess with that in mind, the MBTA Communities Act seems like not a bad first step. Most towns simply complied with the law. A bunch did a decent job. It will generate new housing. A bunch of housing advocates seem to be moving on to the next fight.
I agree, this law has too many loopholes. I guess I'm a bit more optimistic about it generally.
