Cookbooks: he's recommending specific cookbooks which he thinks will make you a better cook. As he says, lots of them are crap, as are lots of the recipes and tutorials on the internet. You're paying for curation here more than the content itself.
Pots: Keep in mind that a "10 piece" pot set is really one 5 pots or pans, which is not that much. Having the correct size pot or pan for the quantity of food that you're heating makes a big difference in how things turn out. (For example, when sauteing onions & vegetables you really want a fairly full single layer.)
Whisk: I'm sorry, but it really is an essential tool
Ice Cream Maker: I completely agree, and I'd be inclined to ditch the whole "desserts" section.
Note, that I think there's some debate about what "minimum viable" means here. The stand mixer falls in this grey area, I think. You can probably get away with a good hand mixer (as he acknowledges) but the stand mixer is more versatile and time saving.
