Sure. You could. But there's a big step between it being possible, and being (what the author implies) a moral obligation. In fact, there's probably a big step between it being possible and it being worth it. If Uber actually got big enough that it became one of the only transportation options, then they might have some kind of moral obligation to setup a phone tree to help people who don't have any other options. But I don't think they're anywhere close to that.
