The screw up to the Blizzard economy will be temporarily and will be corrected in less than a day.
Why do you think this?
If by "corrected" you mean the user will get their stuff back quickly, that isn't so in my experience. Sometimes, some stuff will be restored quickly, but it might take days or weeks for some of it, and chances are that you'll never see some of it back. I'm not sure how they do logging, but such delays imply that it must be pretty human-intensive to get a record of what's been taken and restore it.
I thought you were referring to the macro level (ie someone selling all your stuff). I think from the micro level you probably lose your char but no one else in the universe is going to be affected significantly.
