It would seem to me that libertarianism seeks to end a problem inherent in human nature; trying to justify one man’s self-preservation with another’s. Mises is correct in his view that populations, subject to resource limitations, interact with each other in order to better their situation and change what they view as impediments to their prosperity." Unfortunately, sometimes these interactions aren’t as beneficial to certain parties as they would like, and disputes arise. So populations engage in systems of cooperation and contract with the intended consequence of coverage under the law for both parties.
These systems have a tendency to grow and expand as new populations make a need for ever more resource and ever more coverage under the law. People, being in control of these systems tend to use them to what they see as their benefit. As one man uses it for detriment, another uses it stop the first man. As another uses it for benefit, another seeks to use it to siphon from the benefit. As a result the the system becomes bloated, inefficient, and corrupt.
But this problem is much like a rotting strawberry. The problem isn’t that it is a strawberry, it’s that it is rotten; “It has been said that all Government is an evil. It would be more proper to say that the necessity of any Government is a misfortune (James Madison).” Whether through a formal state or not, the same problems will plague any system.
It is the job of men to check their system every once in a while, find, study, and eliminate the problems that plague their society. "If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place, oblige it to control itself (Federalist 51).
With the removal of state institutions (making no value judgments) it is the private agents who adopt the role of government. But, “even in the panic of 1819, when our country was largely laissez-faire, by their own accord, “Banks continued to expand in number and note issue, without the obligation of redeeming in specie, and their notes continued to depreciate and fluctuate from bank to bank, and from place to place (Rothbard).” It is the tendency of the public to want cheap credit and high wages. And though these two things are seemingly incompatible, it has been the effort of many a human to reconcile these differences.
Rothbard later shows the letter of an early american writing to a british gentleman saying, “you find it difficult to comprehend, why persons who had a right to demand coin from the Banks in payment of their notes, so long forbore to exercise it… The whole of our population are either stockholders of banks or in debt to them. It is not the interest of the first to press the banks and the rest are afraid’”
Banks are businesses, and as such are subject to market forces. Public opinion as a market force will always tend towards cheap credit to pursue happiness, and high wages to sustain it. So banks, and all forms of money lending institutions will always engage in this behavior.
