That's like saying "everything will be ok" without any actual point. The housing system is one example that may have an initial outlay (for land costs I am assuming) but from what I read in the live letter about it - the only real cost to that is the land. Going by how 1.xx economy went towards the end, with them having to reduce a digit as some people hit capped gil - isn't exactly a positive result.
What they really need is a common item that everyone requires, yet is consumed frequently. Otherwise once everyone buys their block of land, makes a pretty house, they will go back to hoarding gil.
