Very good! That's the first lesson in Economics 101.
What makes money money is precisely that, by law, everybody (government included) must accept it as legal payment of debt. (Actually, a legal guarantee isn't needed if everybody is convinced everybody else would accept the medium of exchange; that's how gold and silver became money).
You're stating what is and was obvious to everyone in the thread, including me, and then spinning it as if it's a revelation.
You would have a point about the government promoting a scam if the government refused to accept payment in notes. That the government backs the notes is seen precisely by the fact that it will, indeed must, accept payment in their own notes as legally binding.
The scam has nothing to do with whether or not the government accepts it's own notes, and everything to do with the inflation tax - the profits of seigniorage. Furthermore, since the imposition of this tax is regulated by a non-transparent, quasi-private institution (The Fed), it's not subject to any direct oversight by Congress. But Congress isn't going to ask any questions, because it stands to gain from the Fed monetizing its debt at our expense.
No, actually, it CANNOT do that. Sorry, you fail the second class of economics 101.
The result in such cases is very simple -- inflation. You do not create wealth by merely increasing the amount of the medium of exchange in circulation. Look at, say, Germany after WWI for a vivid example.
No, you fail. Why are you stating obvious positions that I hold, and then acting as if you're teaching me a lesson? Not only do you
not create wealth by monetary inflation, you actually do
transfer it. Based on the fact that we usually have positive ("moderate") inflation, the Fed/Government is skimming at least as much purchasing power out of the real economy to account for the positive rate. Due to the enormous productive power of the US economy, they're actually taking much more,
because of the price deflation that otherwise would have occured had they not emitted any money to begin with. This is a simple concept to grasp. This is why economists prefer to use the definition of inflation which includes the general price level, as opposed to simple inflation of the money supply - the former disguises the true amount of purchasing power that is confiscated, because of the productivity norm.
This is something, by the way, the alchemists of the middle ages missed: if they COULD turn lead into gold, would everybody be wealthy? No -- all that would happen is that gold would be worth no more than lead.
More importantly, the "alchemists" would have been rich beyond their wildest dreams, and masters of the universe. Modern bankers have one-upped the alchemists - they've convinced people to accept pieces of paper, or electronic representations in lieu of intrinsic value. Paper is even cheaper than lead, and ethereal credits on a server even cheaper still.
