If you think deeper ,you understand that inflation doesn't exist because we can print more money. Since we print the debt that we owe we don't owe the debt that we owe because we can print what we owe.
Good. Your post warms my heart. Indeed, we actually cover all our nations deficits (i.e.,Treasury checks that would otherwise "bounce") by printing new money. Then,
later, the Treasury auctions off securities in face amounts matching the new money printed and spent into the economy. Thus, when primary dealers, and ordinary citizens via Treasury Direct, buy these newly issued Securities they are returning to the Treasury the new money previously spent into the economy and leaving in is place highly liquid, Treasury securities. Treasuries, even though we may treat them as a form of money, are not part of the money supply!
The MMT economists treat Treasury securities as just another form of money, albeit an interest paying form. Since treasury securities are not part of the money supply, the
net of the deficit spending process --- money printing>spending>securities auction --- leaves the money supply in the private sector unchanged (remember, Treasury's are not part of the money supply even though Treasuries are a form of money!). It is as though the government bought private sector assets using Treasury securities; thus money printing due to deficit spending is not going to be a direct cause of inflation, at least not via direct expansion of the money supply. Nevertheless government acquisition does increase demand for private sector assets which could be inflationary under some circumstances. Such a circumstance might occur if the government competes for labor into a full employment economy. Think, for example, massive government infrastructure spending requiring lots of labor when labor is in short supply. We have to remember that the government is not money limited unless it chooses to be money limited. So government spending can have a price-setting affect, i.e., the price of something can be set by what the government will pay.
The Securities auctioned by the Treasury become a tool of the Central Bank. When the Fed wants to increase Bank reserves or Bank deposits it can purchase* Treasury securities on the secondary market. This replaces the securities on private sector ledgers with notational money. The Fed doesn't buy Treasuries directly from the Treasury because this would cause the transactions to register in government accounts at the Fed, whereas the Fed's goal is to have these transactions register in private sector Bank accounts.
Treasury securities have many important purposes, e.g., they are a primary tool of the Central Bank, an interest paying store of money particularly useful in foreign exchange reserve accounts, etc. Needless to say, the raising of money to allow deficit spending is NOT one of their purposes.

*To explain where the money for Fed purchases of securities comes from is too involved to explain here, but there is no net additional printing of money when the Fed purchases securities. (It helps if you recognize that the Fed and Treasury are both part of the Government's overall money operation made to look, via legislation, as though they are completely separate operations. ( Of course, those who can't get past the crazy notion that the Fed is a private for profit Banking operation, will never be able to correctly understand Treasury and Central Bank operations.) One of the misunderstandings I see habitually crop up on ET is the belief, by nearly everyone, that the Fed determines how much money to print. This is wrong. Congress determines this when the levels of taxing and spending are set. The Fed simply acts as Congress's agent the way your home printer acts as you agent. The Fed does determine, however, what form money will take in the private sector economy --- transactional money and Treasury securities should be understood as two different, interchangeable forms of money. The Fed also determines interest rates, some directly; some indirectly.
