I would imagine that the list of digital chores of a very busy businessman are a bit more extensive. Even in your list, groceries is something that becomes digital once you're high enough in income.

My grocery store has offered a pick-up or delivery option ever since COVID. Pick-up actually cost nothing extra. It's been years since we used it so I can't say definitively that it's still free, but the downside wasn't cost: it was the ability to pick the best item. If you let the store choose, you'll get the saddest looking produce every time, and the meat that's set to expire tomorrow.
