You have a very limited understanding of what "works" and what is "impossible", it seems. Actual security engineering occurs in hostile environments all the time, in extremely non-perfect environments, with non-perfect tools, and many of its principles (and practices) noticeably make security better for users, operators, and engineers. Similarly, DRM is not only NOT "impossible", it's very possible, very real, and actively used against people today. I suspect if you truly think DRM is "impossible" you have a vastly more limited understanding of security than you think you do.

Computer people have absolutely got to get out of this mindset where impossible means "according to my made up set of Nerd rules", vs the rules that are in place in the world surrounding them.

No, I have a very good understanding of how most of my users, i.e. "normal" people, operate. I would suggest you pick a random relative outside a STEM field and discuss what their security requirements for a blockchain wallet are.

I haven't "made up my set of Nerd rules." I have learned what the general expectations of my users are.
