This is the key, I think. Cries that "somebody should do something" are no more useful in moving the conversation forward than ignoring the issue.
I doubt anybody strongly disagrees that this is a potential problem at some point, whether or not we've reached it already, but there has obviously already been significant discussion on this problem, and barring either:
- A significant change in the problem of 'squatting' in its actual effect beyond annoyance, which doesn't yet seem to be manifest.
- A bold new proposal as to how to deal with the problem that merits discussion.
There's not a whole lot of new ground to tread, is there?
