Not everything that ends up in a pawn shop is given away.
And not everything is stolen, either.
Both you and
@Sky-Knight seem to believe that security in general can be greatly improved by encryption, and I do not. Most of the scams, malware, etc., that end up causing the most damage don't care if there is encryption or not because they are "invited on" to the machine by the user and installed by them, whether they realize that's happening or not. Once it's in situ, it has the keys to the kingdom.
Theft is not at the very top of my list of things to worry about, whether for phones or laptops. It comes back to the fact that the first, and foremost, security you can have is physical security. Once any device is literally out of your hands there are myriad ways to get at the contents. And given how many home users, anyway, still set things up to allow login without a password, or use a PIN like 1234, if a machine like that is lost so is all hope.
Both of your experiences, and approaches to the world as a result, are at great divergence with mine. Your worries are not generally mine, or at least where they fall on the list of things that deserve concern are wildly different.
If I have a choice my home clients, like myself, will have device encryption OFF. I'm not going to apologize for that choice, nor do I feel the need to explain it given all the water that keeps passing under the bridge on this very venue about the messes that it causes on far too many occasions and for what I consider to be very near to zero benefit.
