Again, from walking to buses to airplanes, they serve the same need, to get you from one point to another. How those methods do it is independent of their purpose, even if one is demonstrably better at serving the need. Arguably the only major difference in need is that it's not physically possible to get to some places with some methods of transportation, e.g. you cannot get from San Francisco to England using a bus. I'm also not saying that there must be fewer options, and I'm saying there are other options, not one single option (e.g. walking). I'm saying that it's not necessary for Uber to exist because other options currently exist that fill the exact same niche, even if those other options are potentially not as efficient.
