I generally agree with you but FWIW most of the corn (90%+) grown in the US goes into animal feed, e.g. for cows.
Which is of course its own little tragedy, considering you get 1 calorie of cow for every 12 calories of corn.

Cow eats 40.57 MCAl/day [1]
Produces 45.5 KGS of milk [1]
Milk 610 kcal/liter
Energy of cows milk per day 27.755 MCAL
Cow milk efficiency 68%
This feels high as a gut reaction, maybe calculation is missing energy to grow the cow. Still it shows how efficient they are!
Would love a source for your cow meat efficiency numbers, I'm currently exploring efficiency of fermentation methods to produce meat alternatives and that would be a helpful data point.
