That's fine. On one hand the other saying "no" too much will stagnate the local economy, on the other a city doesn't need to accommodate an infinite number of people moving there. Either extreme will hurt property values in the long run, so there's a balance. I've seen places sell themselves out, I've also seen suburban sprawls where naive homeowners feel good about holding a house 20 years only to make 30% gain.

Nobody else should decide the balance but the residents who have semi-permanently set up their lives there. People considering where to move have no skin in the game, they can pick somewhere else if they don't like what they see or can't afford it. Developers at least have something to lose once they've set up shop, but they're still not raising families there. And by "should" I mean, I wouldn't buy a home in a place where homeowners don't have the most say. Those places do exist, and I'd only rent there temporarily.
