We don't disagree on this at all.  Our difference is about the idea
that underinflated means "less than the tire mfr's maximum allowed
pressure."  Notice the word "maximum?"  It's printed on every
tire.  MAX load X lb/kg at MAX inflation pressure Y psi/kpa.  When
the tire dealer sells you tires, do they inflate them to the maximum,
or do they look in their book for the correct pressures for your
vehicle, and inflate to that (after, of course, spot-welding your
wheels to the hubs so the disks will warp nicely...)?  Actually, who
knows what a tire shop will do...
