Waste defined: devoting 30 million acres of prime farmland to growing fuel for cars
Similary with biodiesel, lay waste to rainforests to grow palm oil for biodiesel

It might be the only option for things that need energy dense storage mediums like aviation. Though algie based SAFs may make more sense and be more efficient.

You still need a way to store and move energy. How big a battery you want on that ocean liner? Or do you only sail when its sunny?
Also, trains. High Speed rail could be the answer to many inter city business flights
IMO biodiesel, ethanol made from sugar cane, and possibly even synthetic fuel1 make more sense than corn-based ethanol for energy dense storage.
(1 use excess cheap electricity for electrolysis of water into H2, combine that with sequestered CO2 to make methane, then use the Fischer-Tropsch process to turn that into liquid hydrocarbon fuel)
