That's exactly the same reasoning we heard during Covid, injecting massive amounts of money into the economy was supposed to be perfectly safe and even a good thing. Definitely not supposed to lead to any inflation. Guess what happened next.
The argument during COVID wasn't that it was "perfectly safe", but that it was better than the alternative of leaving all the people living paycheck to paycheck get laid off and starve.
People just have short memories and see the bad outcome we did get (high inflation) and not the bad outcomes we avoided (unmitigated COVID, economic collapse).
