"A homeowner NIMBYite is exactly the same as a renter that agitates for imposing rent control."

Perhaps.

But a democratic process that generates NIMBY policies is the same as a democratic process that generates rent control: neither outcome is off-limits in our Democracy and both should be respected.

I personally value democracy more than I value land-use policy in one particular place. I further find it disheartening to hear of disregarding democratic outcomes from the very same progressive left that should be championing that process.
