Fuck! I didn't realise there was anyone else out there who understands how money works.
Even then, I think you may be confusing money with currency. Independent nations can issue currency, they can't issue money because money has to have a tangible value in terms of exchange, as well as other, specific characteristics. But yes, the only thing standing between what Jeremy Corbyn spoke about (before running away in fright when undoubtedly somebody from the Bank had a quick word) and independence from debt slavery is the central bank. For a tiny, split second, I was a Corbyn fan. Predictably, that didn't last long.
