I wouldn't compare Uber's abilities to overcome legislative issues within the motor car taxi industry to a similar ability to overcome legislative issues within the aviation industry. For one, the motor car taxi industry had deteriorated to the point where license holders were earning tens of thousands of dollars for doing sweet FA while the drivers of their taxis worked on a 50% cut of the fare and were struggling to make ends meet. If you look closely at that industry you will also find many of these license holders own multiple licences - the system is well and truly broken and I wouldn't be surprised if the government was actually in favour of Uber helping break up that industry. There is a bloke down my street who was a taxi driver all his working life, then settled to become just a license holder of 2 licenses letting others to do his work - he managed to acquire 15 houses in his work life. When the price of taxi licences dropped because of Uber both he and his family began protesting very vocally on being compensated.
I just don't see the same similarities between the motor car taxi industry and the aviation taxi industry as there is much less fat in the latter.
