Depends...
I work in transportation. My current role has me managing a team for a digital freight marketplace as part of the 6th largest 3PL in the country which is an agent for Georgia-Pacific, a Koch Industries company.
LOTS of TP being made and shipped right now. Up to 200% more than normal.
So yeah, critical in the sense of the hoarding. Not essential in the sense of does the public need the amount of TP they're buying? Probably not.
