Should the signing device be bigger, harder to break, or what? I think imprinted in steel is as good as solution as you can have for physically securing something. At the end of the day, physically storing wealth has always been a challenge. It’s going to take some invention to solve that has eluded mankind forever. This is a meat space problem, not a digital one. The alternative is to trust third parties with it, and you are just trusting them to secure it properly. I know which option I’m choosing.

yeah I don’t get his deeper point or what he thinks would be better.
I think both bigger and harder to break, possibly a whole new approach to UX for verification.
Making the device more durable if you have your seed phrase(s) in steel is completely counterintuitive. If anything, we should have throw away, one use, cheap signers for moving material amounts of wealth. As far as using a signing device in its current setup, simply as a facilitator to sign something, I see no problem with them if you are properly securing your seed words. Would you really pay for what you’re asking for?
