T.H.E.Y. must print money at all costs.
Doesn't matter what for, any excuse will do.
But they need to print money. More money than they have printed before (in total)

They also need to print more money than all the new mortgages that should have been, but weren't because of housing supply and interest rate increases.

Any excuse will do... if they fail, no more money.

(in this case, "money" actually means currency - FRNs Federal Reserve Notes)
