As with all ATC services, who is the user? Is it, or is it not, a public good? Is the pilot the user? Or the passengers? How about all the elementary schools over which we fly every day? If it's not a public good, why not just turn it all off? Or, why don't we just pull the CBs on our transponders and radios? Whose to blame then if metal rain starts landing on homes across the nation? Why does ATC exist, if not for public safety?
Here's the end game of user fees:
OPERATOR: "911, what is your emergency?"
CITIZEN: "There's a gang of thugs trying to break down my door."
OPERATOR: "I see from your account that you are a bronze level emergency services customer. As you know, your service level agreement guarantees a patrol response within 20 minutes. As you are a longtime subscriber, you are eligible for a discounted upgrade to gold account status which would guarantee a patrol response within 5 minutes with no additional charge for canine or SWAT. For a mere $5 more per month, you would be eligible for platinum that would also result in dispatch of AirOne and two additional patrol units with field supervisor."
CITIZEN: "Lady, if a patrol unit does not show up within the next 2 minutes I'm going have to defend my home and family with my Remington 870 12-guage."
OPERATOR: "Sir, you do realize that as a bronze level customer you would be liable for crime scene investigation costs and any biohazard cleanup costs associated with the use of your firearm. You could however opt for an upgrade to silver or gold and those fees would be waved. Platinum service would also cover medical examiner and disposal fees for the remains of any perpetrators associated with the incident. We already have your credit card on file so all I need from you for upgrade to silver, gold or platinum service, is verification of your account number and PIN or your personal security question answer."
