Thats incorrect - not all land is equally valuable, so just building more buildings doesn’t mean that housing is solved. Infrastructure around the builds also matter, which means just building denser isn’t a solution. Complimentary services like schools, stores, pubs, churches, skate parks, parks etc change the value of a location as well, and change it differently for different demographics. So making it cheap and profitable only makes it profitable to build - it does not solve the problem of affordable housing.
