My preferred Uncle Jim solution is either:

* Just teach them (as we're all trying to do) and ease them into their own self-custody. But at some point they are off and flying on their own. If they screw up, they learn a valuable lesson. Too bad.

* If I really need to be able to bail them out, I'd maybe consider a 1-of-2 multisig.

But mostly I'm a "learn it + personal responsibility" maxi.
