that could be summed up by saying, "Hey, in fourth edition there are 1000's of outlets from which to receive your level appropriate treasure, it doesn't have to be stripped off a corpse."
the last time I played 4E, we had several 'non body looting' treasure situations, and we were playing a published adventure.
At one point, there was a piece of ground that, when carefully inspected, was actually a fresh hole dug to hide a bag of gold.
At another point, we broke into the private weapon stock of a soldier, and took a magic crossbow (I got that one).
I remember someone getting armor off a skeleton, that we just happened across.
The dungeon was a 10,000 yr old abandoned factory, so it worked into the story that there were areas that our enemies hadn't explored yet.
I asked the DM about how to do treasure in 4E, and he said the only real change from previous versions is that they encourage you to give players what they want/need, instead of rolling off a table of completely random, mostly useless, shit.
