"A world with surveillance pricing will create all kinds of gamesmanship. On airline ticket pricing, that gamesmanship might run like this:
YOU: If an airline’s prices seem high just when you need a ticket the most, you try to look at their flights without signing in to their site.
AIRLINE: Uses cookies or your IP address to figure out who you are.
YOU: Clear your cookies, and use a VPN to disguise your IP address.
AIRLINE: Use
device fingerprinting to identify you nonetheless.
YOU: Switch computers to defeat such fingerprinting.
AIRLINE: Refuses to show you prices at all unless you provide the actual, government-mandated identity that you will use when you fly (“Log in to see price”).
YOU: Ask a friend to look at prices for you, and possibly buy you a ticket (currently permitted).
AIRLINE: Obtains your contact list — a
common set of data grabbed by companies — figures out what’s going on (perhaps aided by AI), and charges your friend the high price too.
YOU: Try a more distant friend.
People could even organize online so unrelated strangers can check prices for each other. Or formal services to facilitate that might emerge."
