Your use of Uber does increase value for other users. Every incremental user increases the probability that someone will need a ride at any given moment, allowing fewer drivers to profitably service an increasing geography. This means better service, on average, for the network. Another benefit is every incremental passenger increases the utilization of the current assets, spreading fixed asset costs around to more rides.
