I had similar concerns around this as well. But for me to educate my friend on how to use a hardware signing device airgapped with a software solution whilst also backing up the seed phase and then trusting him to uncle Jim it for 18 years for someone else when he is still at the custodial hodling (I’m getting him off the exchanges asap!) level it was getting a bit too much. Maybe in a few years when he is ready we can revisit a stronger strategy! Your concerns are super valid and thanks for contributing :) !
