Though paper money should be pretty much confined to the circulation between dealers and dealers, yet banks and bankers might still be able to give nearly the same assistance to the industry and commerce of the country, as they had done when paper money filled almost the whole circulation. The ready money which a dealer is obliged to keep by him, for answering occasional demands, is destined altogether for the circulation between himself and other dealers, of whom he buys goods. He has no occasion to keep any by him for the circulation between himself and the consumers, who are his customers, and who bring ready money to him, instead of taking any from him. Though no paper money, therefore, was allowed to be issued, but for such sums as would confine it pretty much to the circulation between dealers and dealers; yet, partly by discounting real bills of exchange, and partly by lending upon cash accounts, banks and bankers might still be able to relieve the greater part of those dealers from the necessity of keeping any considerable part of their stock by them, unemployed and in ready money, for answering occasional demands. They might still be able to give the utmost assistance which banks and bankers can, with propriety, give to traders of every kind.
To restrain private people, it may be said, from receiving in payment the promissory notes of a banker, for any sum whether great or small, when they themselves are willing to receive them; or, to restrain a banker from issuing such notes, when all his neighbours are willing to accept of them, is a manifest violation of that natural liberty which it is the proper business of law, not to infringe, but to support. Such regulations may, no doubt, be considered as in some respect a violation of natural liberty. But those exertions of the natural liberty of a few individuals, which might endanger the security of the whole society, are, and ought to be, restrained by the laws of all governments; of the most free, as well as of the most despotical. The obligation of building party walls, in order to prevent the communication of fire, is a violation of natural liberty, exactly of the same kind with the regulations of the banking trade which are here proposed.
