I guess the reason farmers co-ops and marinas sell ethanol free fuel might be because the intended use is not on highways. I no longer have any crop duster friends using low lead 100 octane avgas.

The FBO at our airport was great to sell jet fuel during an ice storm and subsequent power outage but I just don't have the nerve to ask for avgas.

Do cows need a catalytic converter? Afterburner? Why waste the methane?
It burns cleaner than lots of fuels. Seriously, we could capture methane from old landfills and use the free methane for something productive.
