The question in my mind is whether the government is likely to do it well and at low cost.
Speculators make terrible mistakes somtimes.
And they try something else. It usually decides that if it just did more of it that things would be a lot better. Blaming speculators for wind-blown trash on vacant city lots is just plain silly. The big trash problems are not on the lots of speculators at all. Rather, the problem is most pronounced on lots that have become public properties as a result of tax default.
