Maybe if Amex also owned most of the airports and had their own airline? And you could only get into the lounge if you were also flying on Amex's airline? And while they let other companies operate lounges in their airports they made sure it was a pain in the ass to get to them?
At a certain point I aged into noticing it was sometimes longreads on one man's journey to find a way to justify a trillion dollar company, and it was tissue thin.
More concretely, if you do this, it's good to then go one more layer and imagine how the people you're trying to write off would respond to the analogy.
I don't think it's worth getting into here, it'll sound absurdist to people who don't believe the lounge sounds absurdist so I'll just be upsetting everyone, but if you run with Beeper's "this is for everybody's safety" position and the credit card lounge analogy...
