Cars, chips, energy, supply shocks etc are what’s causing all this increase in CPI. I would even say there’s not much (monetary) inflation, on the contrary, deflation of the USD might break the system.
Chip supply is higher than prepandemic. Demand is even higher due to fiscal stimulus. Not even worth discussing, its obvious to anybody that has been following the data closely.
Look at retail sales figures on FRED and explain to me how this is not a primarily demand driven inflation:

You and many others are conflating "shortage" with "supply side issues". Shortages can be driven by excess demand just the same as constricted supply
