The issue with just more wards without something else is that without doing something else, it's kinda delaying the issue.

Doubling the number of wards would be great, but we'd probably see the same landrush and everything sold out pretty quickly. The people that have multiple houses would likely still be fighting others for new plots and some people that already have a home may join their ranks. And then if something is done, then it means taking away even more property from people who have invested more time into it.
