> It does. Twenty thousand units represent about 5% of Denver's housing stock [1]. Commit to adding this many units to the housing stock every year for the next 10 years and you'll have solved the housing crisis. (You'll probably need to bail out recent homebuyers, who will be permanently underwater, but that's a separate issue.)
That is only if you believe that more capacity does not induce more demand, which really isn't true as long as the city remains popular for jobs/climate/nature/etc.... People not moving to Denver because the rent is too high will decide to move to Denver if rents decrease (and the demand they add will cause rents to increase, wash/rinse/repeat until an equilibrium is reached). You also have cases where a city becomes even more attractive because of growing density alone (NYC, Hong Kong, Tokyo).
