Value of credit score if you never plan to borrow again?
Only reason I can think of is that having a credit card, or several, is handy for buying stuff on-line, or not having to haul around a fat wallet full of cash.    Of course for some of us, getting the cash back and 0% interest periods are nice, too, even if we don't really need the money.  Same as for instance trying to get good mpg when you're driving, even if you could easily afford to fill up a Hummer.  It's a game, really.
