Depends on if you think in purely capitalistic terms (most but not all Americans) or not (again, most Europeans). I mean one way to think about it is the sidewalk is exploitable by businesses as a potential source of revenue for people who want to ride electric scooters (and other businesses that directly grow the economy) and they can pay lobbyists who drive the engine of American economic growth (lol), whereas you as a pedestrian is hardly doing an activity on that sidewalk that directly contributes to economic growth, so yeah, in a way you are getting your walk down the “free” sidewalk subsidized.
