I feel like this is a complicated issue, because there are two competing values here.
On one hand, fair representation is important, and the idea that every person has an equal say in how governmental decisions are made. One person one vote.
On the other hand, not everyone has the same ‘skin in the game’ for different decisions. For example, if we are deciding if a noisy building should be allowed to be built, someone who lives 5 miles away is not going to be affected by the noise, so they aren’t going to care about that. If someone comes to a community and says “we will give everyone in the community $50 if you let us build this loud building here”, then all the people out of the noise range are going to think that is a great deal. They get $50, and they don’t hear the noise anyway. Why WOULDNT they want to approve that?
So is it fair for the community to decide to make one (or a few) people miserable for years so they get $50?
So things like public review that let a “concentrated local interest group” have more power makes some sense if the thing they are reviewing also has a concentrated local impact.
Of course, there has to be some balance, otherwise we will live in a NIMBY world and nothing will be built.
People naturally have varying levels of skin in the game on various issues. They should not have varying levels of voting power. But that's essentially what public comment process does.
And your natural inclination is to assume that turnout at public comment maps to those people most impacted by an issue. But that's not at all the case! Turnout maps to those most activated by an issue, which is a function of how much free time they have (public comment is generally wealthier and older) and how fearful they are of change (public comment biases sharply towards "no").
I'm fond of asking people locally here how many of them have even considering turning out at public comment opportunities to support new apartment development. I've never met someone who has, even though people here are broadly supportive of housing. But go to a Plan or HPC meeting: there's a line of commenters out the door opposing the apartments.
Public comment is antidemocratic.
