> These 2 sided market places require having a large supply of drivers and riders to be viable. No, they don't. They could just hang out outside of big crowded events, like the end of a stadium concert, or rush hour at the airport. Or whatever the peak crunch point is for the existing service. It would be trivial to make at least some money doing only that. Then the existing service sees its margins eroded. And so on. There's just a ton of handwaving here, but there's no mechanism for a monopoly. Burden of proof would be on your side to demonstrate it. It's absolutely trivial for customers to switch, there's no way to lock them in. At least some people would do it literally to save $10 on a single ride to the airport. And you don't need a fleet to take one person to the airport. Or a couple. Or to strike a deal with one large company, or airline, or whatever. Acquiring a monopoly is pointless if you can't defend it. And you can't unless you can constrict supply or lock in demand. Uber and Lyft can't and aren't ever going to be able to.
