Yeah but frequent flying businessmen are also the kind of people who will do research and pick better options quickly if they are available, it's not plausible for Uber to have a permanent monopoly.

One of Uber's massive problems is lack of predictability. When going to/from the airport I can't fuck around with surge pricing, I need to be able to have a travel budget that doesn't change sharply for situations out of my control. I don't want to miss planes. A service like Blacklane (which by the way is now in the US and is growing very quickly yet seems to rarely make the articles that talk about Uber's competition) neatly solves that problem for you, and generally has better service and more professional drivers.

I am a frequent flier and your idea that there's zero-incentive to have a backup or alternate option to Uber ready to go doesn't resonate with me. Uber isn't reliable enough to forget about other options, and as long as those exist and are viable Uber's supposed "monopoly" strategy will likely be regarded in retrospect as expensive and stupid waste of capital.
