Yes -- but we are not talking about that we are talking about selling goods for which you have no record of purchase and obtained through theft.

You are taking a pretty bit straw man here -- is your claim that there is no way to enforce procedures to curb stolen goods while selling other goods? I think every other seller that has been used as a fence in history would beg to differ -- just go to your local pawn shop.

These are criminals, they can install microsoft office and create fake proof of purchase.

Completely pointless idea.
