Apparently, it WOULD BE possible to completely kill off the legacy taxi industry given 10 years or so of artificially subsidized pricing. So I understand the concept of disrupting a previous oligarchy, replacing it with a new monopoly, and then profiting through rent seeking.
But where are the barriers to entry that would allow Uber to solidify as that new monopoly? There's already Lyft today... and once Uber starts to charge their true costs, then we'll likely see numerous other competitors emerge to compete on price. Ultimately, they're just a phone app! Most Uber drivers today are running the Uber app and Lyft app side by side anyway.
The usual playbook calls for the early leader to pay off politicians, and have them write new laws or regulations that raise the barrier to entry for future competitors. But Uber's playbook has been to take an antagonistic stance toward politicians, rather than buying them off. So what's to stop some newer competitor from beating them on price... or some huge company to swoop in after Uber establishes the market, and beat them by cross-promoting and leveraging their other lines of business?
