Many of the start-up lessons here are those preached by Eric Reis, Steve Blank, and others. I don't think this is a broad treatise on how food start-ups won't work.
Also:
..."things no responsible person would ever not know before even considering raising money." ...
...classic marketing grad trying to do startup things...
...over-exuberant and irresponsible entrepreneurs...
not sure how you don't see this as ad hominem critical.
