Usefully, this blows away the fractional reserve/banks create money conspiracy theory: anyone can create circulating medium (IOUs), but they are limited by their ability to (eventually) repay in Real money (eliberate capital, real=Royal, i.e. authorised money from the state). Attracting money still relies on genuien economic activity, and backing notes up with wealth.What the article doesn't mention is, were the Irish transactions taxed, that's usually been the thing that has hampered LETs scheme, because the British state has always asked for tax in sterling even if the transactions were in lets. there is an argument that it is the tax system that backs up fiat money.
