Forget for a moment that stocks, bonds, commodity contracts, mortgages, and bank credit lines are currently no more than lines of computer code. In the pre-computer days people were paranoid about buying stocks even though they got a nice physical certificate to hold in their hands. And before stock exchanges or banks came around some people were I'm sure, wary and untrusting of any sort of paper currency or receipt exchange system that preceded paper money.
