Of course I have a philosophical difference here. There is always a limited pool of money to be spent on government services etc., always more to get done than can be done. Revenue raised by the government is typically done through taxes (income and sales), and usage fees (transit, licenses, etc.). The more you use general tax revenues for non-necessities - like getting you to the airport (which I consider a luxury), the less is available for necessities (education, welfare, healthcare, and partially publicly subsidized transit). Now if they want to include the cost of this operation in the taxes charged when you buy the tickets (thus raising the cost), then I am fine with that too. But NOTHING is every free - it comes at a cost - in this case at the cost of another service.
