So I have NO idea why a Diablo 3 game with a centralised AND controlled IN game trading system should not have it.
And WHY you would want a non internet game in an era where you are on the internet the moment you push 'on' on your PC.
Diablo 3 is NOT exactly an I pad (transportable game system) either.
D3 needs to be played on a PC with a mouse: have fun trying to play a game with a mouse while on the road.

it is NOT that 3 bank accounts were cracked that the other 10.000.000 bank accounts should no longer use the internet and the whole world would explode.
With uncontrolled LOCAL clients tampering with their bank accounts ... this WOULD be the case though: 9 million of the 10.000.000 would dupe their bank accounts and the bank system (and economy) would blow up.
Not with a server controlled D3 system. Proof is there: NO long term massive duping of 1 item getting copied into oblivion. Simple: because the server controls and stores your item, which makes for a pretty secure security in 99.99999 % of the cases.
By your theory there shouldn't be an internet at all... because somewhere in the world someone is trying to break into some SQL server system...
What an attitude. It simply shows you are hanging in there on some straws.
You simply can't offer a solution of a local client copy of D3 that would not kill the game (by being copied, cracked, duped) before it would even launch. Bad for Blizzard and even worse for players as the game would be total meaningless.
