> There’s only so many empty lots you can build on before you have to start buying existing buildings and remodeling or demolishing them

Saying this is a problem would imply people should never be able to sell their homes or move or anything, somehow the "anti gentrification" crap always comes back to shoving minorities into ghettos

>You can only build y amount on x amount of land

There's this great "new" technique of putting houses on top of each other that would let us build more :)
