Yeah, I agree. I think the change is a step in the right direction to address this specific concern. I think there will be some unintended consequences like loss of tourism dollars which will impact small business, but those concerns seem less important to voters.

Still, I fear that people generally look to politics for simple, one sentence solutions to problems which take decades to manifest.

Barcelona is the 68th densest city in the world. You look at a satellite map and you can see they have a very well planned city layout. It's dense and filled with tall buildings.

At some point the only lever left to pull is outright banning of foreigners. I'm not condoning that policy - just trying to highlight the futility of attempting to protect a desirable area from overpopulation.
