When populations are half what they are now, housing will be much lower than half the capacity of what it is now. Housing requires constant expensive maintenance (as anyone with a house will quickly point out), but when population is half what it is now it won't be a random sampling of our current population. It will overwhelmingly be geriatric and unable to perform the maintenance that keeps houses from crumbling into the ground. Nothing about a shrinking population makes for a strong economy.
