If you understand all that and still advocate a monetary policy that targets 0% inflation..... I'm not sure what else can be said.
To be honest, I don't advocate any monetary policy. I would convert the Federal Reserve into a petting zoo.
Well that's an easy way out of the discussion. A government cannot issue currency without having a monetary policy. It has to spend money on something, whether it's bombs, roads, educational institutions, space programs, programs to support disabled and elderly folks. And it has to tax something, whether that's income, wealth, etc. To be clear, it doesn't need to tax in order to spend, but to give value to the currency. The mixture which a government does those things, in addition to the regulations it places on banks, which also have the privilege of creating money is what makes up the monetary policy.
The main revelation of MMT and chartalism is that money is in fact a creation of the state.... and therefore it's existence can't be separated from law itself, nor from the policies that state puts in place to spend and tax back that currency. If your goal is to not have to worry about those policies and their implications, sure it would be nice if gold would play along and readily make itself available to our government at the exact rate that we needed it and then disappear when we didn't need so much. But the government that creates the money cannot remain agnostic on the matter. Every tweak to nearly every law, effects the very nature of what our money is.
Which gets us back to the Abraham Lincoln quote:
The privilege of creating and issuing money is not only the supreme prerogative of Government, but it is the Government's greatest creative opportunity. By the adoption of these principles, the long-felt want for a uniform medium will be satisfied. The taxpayers will be saved immense sums of interest, discounts and exchanges. The financing of all public enterprises, the maintenance of stable government and ordered progress, and the conduct of the Treasury will become matters of practical administration. The people can and will be furnished with a currency as safe as their own government. Money will cease to be the master and become the servant of humanity. Democracy will rise superior to the money power.”
