I guess that is an easier system to implement, but that's obviously less ambitious and much less magical.

Why does Amazon do one day shipping? That's also huge overkill for 99% of the stuff they sell. They do it because consumers want it, and will instantly forget about all their disdain for Bezos, who btw seems to be growing in unpopularity by the hour, for a more streamlined and hassle free product. I'm not a huge introvert but my instinct is already to do self checkout. I can keep listening to my music, don't have to do the "alright please insert your card" dance, etc.
