Clever,
It depends of the meaning you give to "silver shortage". If for you it means no silver at all on earth, you're right and we'll never be in shortage of anything. But now the price of Comex is the price of the paper silver and don't reflects the price of the metal. Did you try to buy some?
Take a look at this link...
