I can sometimes be impatient, if after visiting one locksmith then having to go to one of only two in town and being told, no the card is not enough, me I would have told them in a lot of words that they just lost a potential lifetime customer and I would tell them I'll be going to the local hardware store to buy a competitors lock and key. Most of the time I am patient enough, but run-around for no reason, no thanks. Even though I am sure a new lock would have cost more, I may have found a better more friendly company to work with in the future.
There are a lot of different sets of keys in the internet realm and other means of identity verification. In 16 years things will change, will a key you have today for an infrequent usage still be remembered or viable in sixteen years? For me the answer was no, even though I have the disk, and the disk key code, since I registered it on steam with a different steam name and different email and had not accessed the game it 14 years likely, it is no longer playable.
I have gone through a lot of computers in that 16 years, and a lot of e-mail address, and a few various notebooks, (the paper kind). With moving several times during that 16 years, things get lost, misplaced or tossed out. I don't even remember what my very first internet e-mail address was.
hahaha - I said this the first time I went ni there. It is of course not their fault as an onseller/servicer, but I made it clear that this is ridiculous.
I think this is something that the digital world has to work out, the protocols can't keep changing as people age, people can't keep up with the learning, it is too hard to keep chasing the latest. All of the photos that people take these days---- must will end up deleted at some point, on purpose, hardware failure or just lost.
