I think you may be taking him a little too literally. He's criticizing that position as much as he's endorsing it. (The context is that he's commenting on a sort of "financial services for The Youth Of Today" product, and he's saying: "yeah, from one perspective this is silly because those people should just be investing in index funds; but that's also the perspective that says they should never actually be spending anything, which is pretty unreasonable when you think about it; so why shouldn't one thing they spend their money on instead of robotically trying to maximize it be financial services that they enjoy more?"
I don't see what consumption habits have to do with picking investments.
He's suggesting that investing with this company called Stash might best be viewed as a variety of consumption that happens to produce not-completely-crazy investment as a side effect, which makes it look less like a rather crappy sort of investment and more like a more than averagely productive sort of consumption.
(Is it reasonable to see it that way? I dunno; it sounds rather contrived to me. But that's the argument he's making.)
from one perspective this is silly because those people should just be investing in index funds; but that's also the perspective that says they should never actually be spending anything

More word salad. What in the world is "averagely productive sort of consumption"?
I think classifying all this under "marketing nonsense" is much more productive.
