This is amazing. He just spelled out for you in great detail the sort of problems that arise in practice in the real world every day and you dismissed them out of hand as being unrealistic. I think you are far more sheltered and far less experienced than you realize. This sort of attitude is exactly what leads to these sorts of things becoming problems in the first place!

Yes, they will do that precisely because they do not trust technology to work for them because it frequently does not! I have family members like this. I log in to their accounts on my devices for various reasons. Even worse, I run Linux. We run in to these problems frequently. Spend time helping technically illiterate people with things. While doing so, make a concerted effort to understand why they say or think some of the things that they do.

Edit to add, I find it amusing that you make fun of his seaman example. Almost that exact scenario (in terms of number of devices, shared devices, and locations) is currently the case for two of my relatives. Two! And yet you ridicule it.
