Easy, they build up on new places, which they aren't allowed to do now.

  The parent asked about what happens after we've built up. Unless population growth grinds to a halt, the buildings will have to grow taller still at some point. If the market needs 20 floor structures today, and 40 floor structures in a decade, he asks how do you take 20 floors of people out of their homes in order to tear down and rebuild sufficiently dense housing.

    Build up more as tech gets better (i.e. taller buildings)? Have better transport so the boundaries of the city get even larger (e.g. twin cities)?

    Most large cities, except for Hong Kong, still have plenty of room to build up. You don't tear down the 20-floor buildings to build the 40-floor ones, you tear down the 6-floor ones in the next neighborhood. It's much cheaper to buy them out.
