You bring up some good points, but this is an overstatement. You haven't convinced me to give up on what is an emerging technology.
You leave out some important details. Switchgrass has low fertilization and herbicide requirements, for starters, and it's a hardy perennial with a complex and well-established root system, to boot. Also,
some have found ways of getting 4 units of energy output for every 1 unit of input.
For years, it was ridiculously expensive to extract oil from the tar sands in Alberta. Almost not worth it. But they've developed the technology to make it more viable and rewarding (though the environmental factors are questionable). Canada is now poised to be the next Saudi Arabia. Hoser Canadia?
I believe the same could be done with biofuels. I wouldn't give up so easily.
