I think my criteria are very reasonable. In order to do any kind of cost/benefit analysis, one needs an estimate of both.
Or, we can all just wave our hands and sing songs and expect politicians to DO something.
It's ridiculous. And for folks out there to THINK governments are really going to tackle this issue is amazing to me, a complete lack of any rational analysis.
I liken it to the debt/deficit issue. Politicians promise to DO something, without any coherent plans, and then of course if elected they do nothing.
