Sure, but if you believe the scooter-sharing market will end up being dominated by a few companies (because consumers will prefer to use whichever company is most likely to have a scooter available wherever they are), then it's not unreasonable to bet on one particular scooter-sharing company ending up with a large percentage of that market.
The issue is the value of this particular scooter-sharing company here, not the value of the global scooter market.
