You're definitely right about the difficulty of change, but I think the bottom line remains: gasoline for commuting is not actually used anywhere in the process of producing the relevant goods/services. The raw fact is that hair styling can be done without using 4 or 5 gallons of gasoline a day. Gasoline plays no functional role in providing the service of hair styling. So why should we say that gasoline is needed to provide hair styling's portion of the GDP? That portion of gasoline should be struck from "oil used to produce goods/services" because, just as a matter of bald obvious fact, the gasoline is not being used for hairstyling. There's no physical connection between gasoline and hair styling. People were styling hair for thousands of years before gasoline was even discovered.

This means that oil intensity is greatly overstated because it includes large volumes of oil being consumed for purposes other than actually providing goods/services.

Say your furnace or telephone stops working, and you call for service.  The tech will probably drive a very inefficient truck to your house.  He's probably driving around all day to answer calls.  Suppose you have a sore tooth or strep throat.  You probably have to drive to the dentist's or doctor's office.

Without the gasoline or diesel, you'd have to hope that one of your close neighbors was a heating contractor, telephone lineman, dentist or doctor - all with home equipment.  You might get Aunt Mildred to style your hair, but accessing goods and services generally requires transportation.  

Maybe planning or high gasoline prices will induce people to redistribute essential services more locally.  Or maybe some will wait longer for services, do without or be more self-reliant.
