I'm finding that people can relate to the idea that Bitcoin and Litecoin are the Mastercard and Visa of the future, more than they understand the gold/silver concept. They can understand that they can go anywhere in the world and spend BTC as a world currency as a convenience. I know that Bitcoin is theoretically capable of handling all the crypto currency needs once it scales, but I think , just as with gold, people will be storing it and increasing the need for litecoin in the marketplace, just as with silver.
