Can't "gas stations" just swap out your empty battery for a charged one, the way you can swap out an empty propane tank and $20 for a full one?

A few years back I worked on the web presence for a company focused around doing exactly that (along with a network of charging stations).

It didn't quite work out as planned:

I was thinking more like a car battery meets a propane tank- easy enough to just lift up and take inside to the attendant.

One day, I guess.
