It's not an argument. Getting people to "stampede" to you is trivial - just drop the prices well below market average, and the herd will quickly follow, regardless of whether or not your service is actually better. Doing that is difficult (that's the point of competition), but becomes much easier if you can blatantly break the law and get away with it.
Come on, there's no way you can say taxis are superior to a frickin button that you press to instantly get a car. Even if the prices were the same, I'm pretty sure most people would still choose Uber.
