The only argument i ever really bought was the origin of agriculture. and even that is pretty suspect, but i still think it's a decent argument.
10,000 years ago, pretty much everyone was a hunter gatherer. Humans can survive on pretty much anything from seeds to whales. There's not really much need to control the environment to maintain a food source in that context. Yes, there will be lean years, yes there are other populations you're in competition with (but they could also be food...)
In any case, the argument goes, somebody stumbled on fermentation. The desire for regular access to whatever plant got you drunk might actually be enough to become a farmer. It's tough to say. I think it's plausible, and probably part of the whole story.
Hunter gatherers were healthier and longer lived than their farming counterparts. I think that's still true of the few hunter gatherer cultures that remain. Food security is a good reason, but for a human, especially a hunter gatherer, everything is food. Alcohol security though, that's a pretty compelling argument. Perhaps not for you personally, but i'm sure you've met people that would agree. Addiction is powerful.
