Something interesting you might not have realized before (I didn't!) --- virtually every American craft whiskey you can think of is owned by some huge company! To wit:
* Basil Hayden - Fortune Brands
* Knob Creek - Fortune Brands
* Eagle Rare - Sazerac
* Buffalo Trace - Sazerac
* Blantons - Sazerac
* Pappy Van Winkle - Sazerac
* Elijah Craig - Heaven Hill (Christian Bros)
* Black Maple - Heaven Hill
So one reason why it's apparently hard to be an indie whiskey distiller is that the major brands have owned up a lot of very high-quality craft distillers already; as the article points out, unlike with beer (where Coors really does suck), widely-available well-known brand whiskey does tend to be very good.
I think he overreaches with his argument by taking on all of distillery. Whiskey is particularly hard to do well. It's aged for many years before being brought to market, which makes it particularly capital-intensive to enter the market, but not as costly to sustain a proven brand. It's also a spirit with very well-defined parameters; unlike with gin, where a distinctive and interesting new take would be welcome, whiskey is more like wine: the market knows what it wants from quality product.
It clearly must be easy to outdo vodka distillers. Dave Arnold at the French Culinary managed to make extremely high-quality flavored vodka out of pure food-grade alcohol --- an industrial supply! --- for a couple bucks a gallon. So there's an easy counterexample.
Gin seems like another easy-to-enter market, and one where you can bring innovation to market without relying on novelty products. Just use different/better aromats.
I appreciate that Jim Beam is a quality product even though it's at the low end of the quality spectrum, but I don't think he did his argument any favors by saying that it was better than any indie craft whiskey he'd ever had, even if it's true.
