A damaged economy is what causes harmful inflation as evidenced by countries like Venezuela, Zimbabwe, and Iran.
If governments are selling bonds that produce negative yields, I would say we are already have a damaged economy.
Governments are printing money and bonds have negative yields, how is this possible? Where is all of the funny money going?
You ignored my previous answer on negative yields:
Its not guaranteed. Rates can go lower and the bond will go up in price.
Bonds don't have negative rates. If they did nobody would buy them. Negative interest rates are applied to deposits that banks have with the central bank. The purpose is to provide an incentive to banks to use that money to lend rather than have it on deposit.
