While it's true most people can't fly around the world to shop, e-commerce brings the shops of the world right to their door.

And sure, middle class westerners don't have a lot of servants that physically work in their house, but that's a very narrow view that misses the point.

The service industry is huge, things like child care and public/private schools (replacing nannies and tutors), restaurants and takeout (replacing chefs/kitchen staff), grocery store (replacing having your own farm and farm laborers), automated home appliances(replacing maids), running water and electricity (replacing servants), computers (replacing secretaries and assistants), Uber and self-driving or even just a drive-it-yourself car (replacing chauffeurs) and of course toilets are a big one...

Many of the ultra rich can indeed afford a roster of servants, to man their yacht, for example, but many of them still prefer not to do so and even do their own cooking and laundry for the priceless benefit of not having to deal with people other than their family in the intimate personal spaces of their home.

Privacy is a luxury not to be underestimated, and illustrated by the fact that your dishwasher and lawnmower will never fall in love and run away together with half your silverware.

Shopping was an example. The point is ultra-rich people jet around the world for utterly banal, trivial reasons, like it's nothing. As you said, e-commerce eliminates the need to fly to shop, but they do it anyway.

Toilets. To not have to empty a chamber pot, nor have to hire someone to do so. Massively under-rated luxury.
