“Could someone fully explain “free banking”? From my understanding, it is if the government sets no requirements on the reserve rate banks must hold. So theoretically, it could be zero or it could be 100%, depending on what the market chooses. The beauty of it is that individuals could purchase different rate plans. A 100% reserve plan would be the most expensive while a 0% reserve plan would be the cheapest. To me, this seems like a true free-market for money/loans.”
This is a pretty good first pass at free banking. There is debate about whether Fractional Reserve banking is consistent with the libertarian property ethic, though. As an analogy, would a valid law rule out the voluntary contracting of an assassination on a non-aggressing third party, or should the market decide? An anarchist might argue that private market courts would validly rule against such contracts, because they are aggressive. So the reserve issue is not cut and dried. Rothbard is a good source for this side of the argument.
“Is any of that wrong? Am i missing anything? How is free banking different than the gold standard?”
A gold-coin standard is what the free market landed on by natural and non-coercive means. This is why the Austrians like it. It is considered to be honest free market commodity money, in contrast with fiat paper, which is worthless and put in place via threat of violence from the aggressive state. Free banking is merely a free market in banking - unregulated, unlegislated, no central bank or coercive banking cartel, no lender of last resort, no legal tender laws, and no banking holidays to protect the banks from bank-runs.
"To me, the free banking system seems better than the gold standard.”
This is too much like saying that cars seem to be better than roads. The two are not in conflict.
“If I am not mistaken, under the gold standard the government would force banks to keep 100% reserve at all times.”
The Rothbardian anarcho-capitalist view is that even private courts would find currencies based on FR banknotes to be fraudulent. So the question is, would it be? If it would, then no libertarian should be in favor of currencies based on FR banknotes. The debate is in the ethical nature of paper currencies based on FR banknotes - not whether free banking is good or not.
“Why not allow the market to decide what reserve rate is best?”
This is fine, as long as the market provides private courts to determine if fraud has happened. From a certain perspective this can be seen as similar to “why not allow the market to decide what kinds of murder are best.”
“Why not allow some people to make deposits backed 100%, and others to make deposits backed 50% or 10%?”
There is no question that such transactions should be allowable. The question is, could receipts for 10% backed deposits possibly become universally accepted as money in a free and non-fraudulent market. If this is not possible, and yet such banknotes were indeed universally accepted nonetheless, would this necessarily imply a mass fraud taking place? If the answer is yes, then libertarianism rules it out.
“Someone on this forum (I forget who) said that a 100% reserve rate would be like buying a Rolls royce while a low percent rate would be like buying a honda. Is that a good metaphor?”
A better metaphor is someone sells you a house which you pay for and take title to, but don’t immediately move in to. Simultaneously, the same seller secretly lends title to the same house to someone else - who moves in. You both hold title to the same house, and since you have not moved in, you do not notice this. Is this fraud, or is it merely efficient use of your house?
“If so, then doesn’t the gold standard force all people to purchase rolls royces?”
It forces people to explicitly contract for either a storage arrangement of their money, or a credit arrangement - one or the other, but not both at the same time, since such an arrangement is deemed to be a logically impossible and purposefully deceptive arrangement.
“Why not allow people to purchase honda’s if they wish?”
So this analogy is not quite good enough.
“If my understandings of the two systems are correct, I have a difficult time accepting the gold standard theory, but the free banking theory is very attractive to me.”
I hope my answers introduce some of the possible ethical snags inherent in (even “free”) FR banking.
