Do you imagine that sand is terribly hard to get? You do have them living in a desert growing rice.What are they blowing glass out of? Do they have magical sand plants?
Aaaaaaaand which nobody has said doesn't happen. They do trade. They don't trade a often or in large amounts.So, they can't make books, like I said, and they'd need to engage in trade, like I said.
Trade for what you need and nothing more is not the same as selling for profit and money. Try this experiment to see if there's a difference. The next time you go to a grocery store, bring some pillows from your house to trade for food. See if they will accept them. Then offer them money. See if they will accept it. If the grocery store will accept your pillows the same as they accept your money, I will concede that there is little difference.And you still insist that somehow trade and selling is an important enough difference to hammer home.
Why would Halfings ever send mail when they can travel(they love to travel) home to get good food and see their parents(they love to socialize)? You're inventing problems that don't exist and then saying, "Look! Look! Problems!"So, you can't send mail home to your folks, because no one can find halflings.
