Nothing is "obvious" in tech any more, because there is simply too much. Two "tech savvy" people will often each have things they think is "obvious" that the other isn't familiar with. And this isn't even a good example of something that is "obvious" to some people, because Google makes it very, very clear that saving the QR code is NOT a backup option. It is labeled only as a mechanism to transfer to a new phone, so one has no reason to believe that it's non-ethereal. Further, the app disallows taking a screenshot. You have to point a camera at your phone. It's mind-blowing to suggest that it might be appropriate to blame the user for not doing this.
