On the other hand, we spend enormous amounts of money on other solutions like busses or underground metro systems in dense urban areas which have significant problems like not taking you where you want to go. If there are systems which do get you where you want to go you might not have to make those up front and gigantic investments in future.
If you have systems which are point to point, then the value of real estate that isn't near a metro stop can go up since you don't have to price in the walk from that place to a metro stop. There are all kinds of fun implications.
Also, scooters might only be step 1. Maybe self-driving scooters with a 5 mile range are step 2, or something.
So if you compare to existing systems you can argue that scooter valuations are cheap if that's the direction we're going, though that isn't certain.
