i agree in principle with your argument, but i imagine the only way to properly track historical players of that machine is if they kept some sort of ledger or database on every single user of the machine, which probably means they'd need to store your personal information somewhere indefinitely. not sure too many gamblers would be cool with that.

It's called a rewards card, and almost every frequent slot machine player uses them because they get perks.

Players who spend a lot of money already let the casino track them on purpose so they can get perks.
