It's only wrong if it doesn't work -- but it does. Economists aren't 100% sure why, but it does.

The fact is while the debt has exploded, the total cost to service that debt has collapsed. The US is now paying less interest on its sovereign debt than before the COVID stimuli. Explain to me how it's stupid not to take advantage of this?

The reality is when you take on debt, the only thing that matters is what you choose to do with it. If you use it to generate economic activity - and hence revenue - that's a good investment. If you don't, that's a bad investment.

Now, you can "circumvent" this by investing your money like you're supposed to in literally anything.

The cost of debt has dropped would be a more accurate description. Well... just because you can take out more loans does not mean you should. The issue is really how long you can refinance the debt for, or can you outgrow the debt, otherwise you’ll be forced to inflate it away. The cost of financing will not be this low forever and it’s still a few hundred billion of interest each year. Still, we should spend money on infrastructure and cool tech while we can.

Yes, and that the only point of taxes is to reduce inflation, since the govt doesn't need taxes anyway since it can print money. Taxes don't even cover the cost of govt expenditures so it makes sense.

Broadly speaking the tools of monetary policy available to reduce inflation are:

(1) Increasing reserve rates for lending. This causes the circulating supply of currency to go down.

(2) Increasing interest rates for lending. This reduces the demand for borrowing, which is largely fractional reserve. This also causes the circulating supply of currency to go down.

(3) The Fed unwinding its balance sheet by selling bonds. They collect the cash and remove it from circulation. They can increase the circulating supply by buying bonds.

Taxation doesn't change inflation, to the best of my knowledge, as before and after taxation the same amount of money exists in the circulating supply. Taxation is fiscal policy.

The government doesn't print money per se, the government can borrow money by selling bonds. This just reallocates the existing money supply. The overwhelming majority of US government debt is held domestically by US persons. This doesn't change the money supply either, unless the Fed steps in.

Fiscal policy affects inflation. You're thinking of inflation as "the money supply / total of all $", but that's only one definition or part of inflation. Generally, you would also describe inflation as the price of things you buy going up or down (CPI). Say you ratchet up the effective tax rate to 90%. Everyone's going to have a whole lot less money to buy extra things. Some things with fixed raw input cost still wouldn't budge much. However now that people's monthly incomes have gone from $5000 -> $1000, you're going to see houses, education, Pelotons, and other extra income sinks, have their prices fall precipitously.

The point of taxes is to create demand for the currency in the population. The government can then promise to pay people in its own currency so that it can provision itself with staff, goods and services.
