I tried to give you a nice simple example of how your blanket assertion that insulation doesn't delay the inevitable, and I demonstrated that it often does. Maybe my example wasn't simple enough for you?
Nosey, all you had to say was - "yes, R&C, you may have a point about insulation in the scenario that you mention. Placing an ice lolly in an insulated cool box will actually delay the inevitable - ie. the lolly melting."
I think you were just talking at cross purposes. Your simple example is obviously and undeniably correct. But it is also true that, by itself, it is of little use when it comes to understanding a complex dynamic system.
