I asked a similar question in a similar thread recently. The answer that made the most sense was that the Fed feared future inflation. If you've done QE then you can just sell the stocks again when you want to limit inflation. But if you've done helicopter money then you're stuck.

The Govermment has something called ‘taxation’ in case that happens.

Really, the Fed has something called "raise interest rates" in case that happens. Something they've been wanting to do since the housing crisis and the primary reason they can't is that there hasn't been enough inflation, and raising interest rates against low inflation causes deflation (which is very bad).

Congress could do everybody a huge favor right now by printing quite a lot of money and handing it out. Which would address the deflationary forces created by the demand destruction of the coronavirus in the short term and allow the Fed to actually raise interest rates after the pandemic is over.
