Presumably you didn't just keep that money sitting in your own bank account though - you used it to buy something or pay someone, and their account was often at another bank. If a bank issues too many loans where the money ends up at other banks without counterbalancing transfers of money in, it eats away at the reserves they have available to settle those transfers with and that's how deposits actually limit banks' ability to make loans.
