That comment is a bad take to be sure, but it isn’t really about eliminating every vehicle in existence. We’d still need individual vehicles to serve for delivery and emergency services, as well as a bunch of other stuff.

The main thought is just that it’s a bit silly to have half the population driving a two tonne vehicle to the grocery store. There’s already communities where golf carts are used instead of cars.

The whole concept of ripping out every road and installing solar tramways is just as much a nonsensical extreme not worth taking seriously as ‘what do I do if I order a computer and I work from home’. I get your use of the example though, it is the equivalent counterpoint.
