That took a whole lot of words to state the extremely obvious Ken. Silver comes from the earth, not mines or jewelry stores, how true. I think I remember something about that in my undergraduate work in geology.
You keyed in on the wrong word, you should have paid more attention to "irresponsible" instead of "waste". A lot of fuel, energy and most likely pollution and its cleanup paid by taxpayers (if cleaned up at all) went into taking that silver out of the ground and processing it, and manufacturing products and moving them to market. Dumping it back into/onto the ground where it has nearly zero chance of ever becoming economically feasible to mine it is irresponsible, just like throwing your tin, aluminum and plastic in the back yard is irresponsible. You have a very narrow and producer-centric view of the economics involved-we all pay the cost.
