Don't worry about it. It's a difficult subject for most. I have given literature references here for those interested in delving deeper. If you later become interested, you can look those up.Dude, we went over this before. You can get into semantics and differences into circumstances and stuff all you want, but U.S. Treasury bonds are a promise to pay a sum certain in the future plus interest. That is exactly what the most basic definition of debt is. The U.S. government CAN default on its Treasury obligations, just like any other non-government debtor CAN default on their debt/loans if they cannot repay them. The U.S. government CANNOT default on U.S. dollars in circulation, because they are not debt.
Probably only difference in substance is that the U.S. government can (although maybe indirectly), pay off its DEBT by printing money, private debtors cannot.
Its debt, dude, no matter what spin you try and put on it.
You're on the right track here, but actually it is even easier than that. When the Central Bank buys Treasuries, the esatz debt they represent is eliminated and replaced with an equal liability in another form. And the C.B. didn't even have to print the money (again) to buy them. Remember, the money was already printed before the ersatz debt linked to it was issued. (To understand this completely you have to know what happens to Treasuries when they are on the government side of the ledger, i.e. on the Central Banks balance sheet.)Probably only difference in substance is that the U.S. government can (although maybe indirectly), pay off its DEBT by printing money, private debtors cannot.
What the C.B. is doing when it buys Treasuries is simply exchanging one form of money for another. This is what Japan did when it got rid of ~50% of their ersatz debt. This did not reduce their total Treasury liability. They just stopped calling the liability "debt" , once it was in the form of bank deposits. So everyone in Japan would sleep easier.

When the C.B. does this kind of thing they don't change the amount of money in the private sector. Treasuries, cash and electronic notations in private sector accounts are all liabilities of the U.S. Treasury. The only difference between money in the Form of Treasuries and that in the form of Bank notes, coin or accounting notations is the future interest owed on Treasuries. That interest is a non-discretionary budget item that will first make it's appearance in the private sector as an account notation. To the extent Treasury interest contributes to a deficit it will first appear in the private sector as newly created money and later as a part of a Treasury security. (Remember, all New Treasuries issued are linked to new money already created and spent into the private sector, which in turn is linked to deficits.) The principal on, say, a bond in the private sector is the same as an equivalent amount of Ben Franklins except that when it is in the form of a bond you can't buy a hambuger with it. You have to first convert it into Ben Franklins. Thus Treasuries are not part of M2 until converted. Both Treasuries and Ben Franklins however represent Treasury liabilities. Do not think there is no government liability associated with Ben Franklins please.
