You ignore two other important factors that affect tire wear. Tread and compound. When you take a look at a soft compound mtb downhill tire with aggressive tread, you will notice it will wear down extremely quick, way faster than a road car tire.
Are loads of people using mtb downhill tires (on roads?), or something with a better formulation and less aggressive tread? Longer-lasting tires is a clear incentive.
Knobby tires on a truck/jeep to fetch groceries seems like the same issue but worse. Though either way, IIRC this is a bigger issue when tires are brand-new.
I think you are underestimating how much power/friction is going into that much rubber on vehicles that are thousands of pounds empty and can go 50mph+ and the braking force needed too (which also creates dust). It’s an entirely different scale, especially oversized trucks and semitrucks.
