Wow, it’s almost like building affordable housing instead of exclusively overpriced homes and luxury apartments is something a health society would do.

strongly suspect you're taking the wrong lesson from this, and I recommend you read the actual policy in question here

IZ can be done well, but Minneapolis’s rents fell precisely because its IZ didn’t unduly constraint the building of new market-rate units.

There’s a mountain of evidence that building new market-rate housing reduces rents for lower-income people, because then rich people aren’t bidding up the price of less desirable housing stock. If we don’t build homes for the well-off, those people don’t disappear, they buy up YOUR neighborhood.
