An issue with using fiscal policy this way is that many of the things that are worth spending money on aren't easily movable levers, they are long term projects.

If inflation is accelerating and we need to cut spending to fix things it may be difficult or inefficient to cut the budget of a 10 year infrastructure project. If we need to spend more one year, do we just flood the healthcare system or military with money temporarily?

Changing tax policy frequently creates uncertainty for people investing in long term projects, which increases risk and cost associated with funding them.

I like that there is an academic debate going on about MMT, but there are practical challenges in implementing it. While far from perfect, the current monetary policy approach is easier to implement and change, while outsourcing capital allocation decisions to the banking system.

You missed the "mail everyone a cheque" era?
