The government isn't coming in and saying what you could build and taxing you based on the value of the building. It's just taxing the value of the land without any improvements at all. The developer is going to pay the same taxes no matter what they build, so they rationally should make as efficient use of the land as possible, but that most efficient use is determined entirely by the free market, and they are free to make less efficient use so long as they are comfortable leaving money on the table. If you're not going to do something with the land that generates more value than it being left alone, then you just leave it alone.
