It would eliminate that fear of forgetting the key.
Again, it comes down to your threat model. Key stored in more locations is potentially compromising security, but is a trade-off everyone has to consider. It still prevents disinterested drag-net style data leakage.
If you are targeted by the big bad, I doubt my operational security would be sufficient to protect me from a motivated attacker. I suspect that there are vulnerabilities in my TPM/random number generators/encryption software that are exploitable. An evil maid or even just a camera positioned over my keyboard would probably be sufficient to grab my data. Plus those $5 wrenches.
Yeah my threat model is that nobody cares about surveilling me in particular right now, and I’m not in a jurisdiction where rubber hose cryptography is very realistic. ADP will protect me easily from most attacks short of someone blowing a zero day on me.
