Growing a city with a growth boundary is very, very easy. All you have to do is tear down some older structures, and build new, taller ones. Or fill in empty space. The reason this isn't done is purely because of stupid zoning laws and NIMBYism. I think the solution is pretty simple: make a state law that bans municipalities from making any zoning laws at all, and only allows the state government to control zoning.
