hmmm...is this actually true?

"Gold and silver are 'our money.' That's why you don't pay sales tax on gold when you buy it and no record of the transaction is necessary."

My dealer in the US says he has to take your name and address, etc due to "Patriot Act" law provisions as a means to make sure they are not selling to "terrorists." This is only for transactions over $1k. So is there really anonymity here in the states?
