You're mixing up home builders with landlords. The latter aren't fulfilling housing demand: they are capturing it by outcompeting people who cannot afford property prices (prices driven up by buy-to-let demand). You say that landlords are intrinsically bad: lots of people agree with you on that... I stop short of it, since there's a minority of people for which renting is a preferable solution (at least temporarily) and nationalising the whole housing market is infeasible.
