I think the problem people are having with the suggestion of "A living world is a useful tool to prevent the 15MWD" is that it has a (probably unintended) negative connotation to it - that it's something you employ specifically to discourage a playing style.
It conjures images of the DM saying to himself "Darnit, they've gone off for a rest again! Okay, what can I come up with for the monsters to do in eight hours that'll teach them a lesson?"
Whereas I think the intended usage is more along the lines of "Okay, they're out of the picture for the next eight hours. What's everyone else in the area likely to be doing in the meantime?"
Basically, it shouldn't be viewed as a tool to encourage or discourage certain types of behaviour - it should simply be an aspect of the underlying game world that needs to be taken into account.
