Re: Is there any kind of valid comparison that has been done to other schemes?
I find this level of personal information access disturbing too. In my (East-European) country, you can walk into a supermarket, pick up a TV set, pay with cash, and just leave (as far as I know - didn't try to buy one lately though). If you actually want warranty as well, you're expected to walk over to a counter - of your own accord, nobody should be forcing you - where your name and address will be recorded on the warranty papers, but there will be no checks of it against anything (at least not there and then).
