There are many reasons why this is wrong. The argument is that #1–the person the bank lends money to, “borrower,” and #2–the person depositing money at the bank, “depositor” each have a claim on the same dollars.
Now, first of all, you have to get past the hurdle that most depositors, if you ask them, understand completely that the bank lends out some of its deposits, but keeps enough money to cover withdrawals as needed. So you have to claim a system is fraud even though both Bank, Borrower, and Depositor know what’s going on. That is hard.
But more importantly, if I deposit money with a bank, I am not claiming the asset. I have a right to claim it on demand. Those are very different. If I tried to withdraw money from my account, and the bank said “no, it’s lent to borrower”–THEN two people would claim the same asset. But if the ATM gives me dollar bills on demand, then I have just successfully claimed my asset.
Simple version: Grain elevators are not banks.
More complex: This is one of Rothbard’s funniest arguments. As you and I discussed in a previous thread, his argument that grain elevators couldn’t do this was based on the fact that the government declared it to be fraud.
So the argument is: Government says X is fraud. X is like Y. So Y is fraud. Except the government says Y is not fraud. So the argument is based on the government’s definition of fraud in the context of grain elevators, and is being used to override the government’s definition that fractional reserve banking is not fraud.
ETA: here is my response from the prior thread. It speaks for itself. The thread itself is useful to read. N.B. DDA’s=what IdahoMauleMan is talking about when he’s talking about grain elevators.
