@yukiame @strypey Currency-issuing states never need to tax in anything but their own currency. Taxes don't finance spending; spending finances taxes. Where else would the first $ taxed come from? #MMT
@strypey Money is _used_ in exchange, & also as a store of wealth, but neither is what money _is_. Money is an accounting credit. It's useful to hold & accepted in payment because it has a killer app - eg. the ability to settle taxes. #Bitcoin, at any price, is not money. #MMT
@strypey Accepting taxes in #Bitcoin would be insane. It would mean surrendering the ability to use the monetary system to achieve public policy objectives. It'd be like joining a monetary union in the absence of political union. Who would do that? Oh, wait…
@mjd @strypey @clacke It's singularly hard to pin down what money "is", I think, if only because there are a number of different groups who all claim one definition of other, the differences in practise are quite subtle, and there is, to me at least, no clear candidate that is strictly a stronger choice than any other.
@pettter @strypey @clacke @mjd The definition used in first year Econ classes (a medium of exchange and a store of value) is at least as accurate as the accounting entries which record those things. Money has been many different things at different times (e.g., seashells and pretty rocks, gold and silver coins, pieces of parchment or paper).
@lnxw48a1 @mjd @strypey @clacke Is it a necessary and sufficent definition, though? When does a particular thing start acting as a money, and how does it stop? Does it need a market? Does it need a market of things other than itself?
@pettter Grammatically, "moneyed" is at least a verb in the present participle, which would suggest that "money" would be the infinite. I'll leave you there, at the thought of infinite money. :-)
@mjd @strypey @yukiame The Hong Kong money supply comes from foreign currency. The M0 is required to be 100% backed by currency reserves. As the HKD is pegged to the USD, I'm assuming the entire reserve is USD.
@strypey ... while also being a market actor. State goes "Here, I'll uphold law, order and defense of property and otherwise stay out. Except I'll be a monopsony on 50% of the goods and services, by taxing the other 50%.".
