Melvinica: I can't even tell you how bad of an Idea that is. And also it doesn't really work with drm free games.
You make it sound like generating infinite copies of the rarest loot is a bad thing.
What do you have against the entire population of every possible game being equipped with the best possible equipment, all purchased for a fraction of a cent? Item duplication exploits cost nothing after all...
That same fraction of a cent could make you an in-game trillionaire. Who wouldn't want limitless money?
The benefit of a DRM free game is you don't even need to wait for the RNG to give you a +50 sword to sell on the market - munchkin mods and save game editors will give you all you need.
Now that I think about it, I think we have just invented the perfect deflationary economy - unlimited copies of everything will soon be available for the minimum possible price.
