Killing Uber and Lyft outright means bringing back the taxi industry, which isn't better for anyone except the cab companies. The biggest benefit of ride sharing for me isn't that it's cheap: it's that I don't have to awkwardly assert my legal right to use a credit card every single time I ride. I'm fine with paying more to ensure drivers are earning a living wage.
I'm not saying that they are not convenient, I'm saying they're unsustainable. Eventually they either will be more expensive or less convenient. The question is how much they can reconfigure society to their advantage in the meantime. For example, their price dumping is causing some governments to cut mass transit funding which will have long term consequences.
