But he’s not correct at all. Supply chain shocks always cause inflation and was the overwhelming reason why inflation picked up starting in 2021. The Iran war also caused inflation with the supply shock of oil. What you’re talking about is the 2% inflation rate goal which no one is even considering changing as that would be the beginning of the end. The 2% inflation rate goal keeps the economy healthy as people freak out if inflation drops below zero leading to cascading events as well as gdp so it gives the economy a decent buffer before that happens. Also why growth is measured as nominal gdp and real gdp.
