I don't think you understand what network effect is. A network effect is where the network raises the costs of switching to another network significantly that they are locked in. ex. FB and your friends.
There is nothing that suggest Uber has a network effect that locks in a user to use Uber. You are talking about a quality effect from the assumption that more assets will lead to a lock in effect but it's hopeful at best. There are no barriers to entry to erode future Uber profits if they make money and no perceived cost of using new entrants services or existing ones.
