Even if you personally believe building large buildings permanently disfigures it, the fact that people are willing to pay for and live in such buildings shows that people still value such "permanently disfigured" cities. Why should people who own buildings/land, and purchased them under laws allowing them to do as they please with the property now be disallowed from building large buildings on their plots of land and sell/rent them to willing buyers? Why should the current renters, who don't own the property, receive superior rights to those who own the property and those who would willingly pay more than them?
