A distinction that has been lost on apparently everyone here.  Please
use accepted terminology.

No, it's still a single file ("pubring.gpg", for instance, is the public
keyring).  I just can't promise that it's still a raw stream of RFC4880
octets.

I have been: your statement is trivial.

Assuming the passphrase is of high quality, that answer is *absolutely
correct*.

If the attacker already has read-wherever access to memory, the attacker
can do orders of magnitude worse than steal private key material.
You're saying here, "if you assume the computer is already in a
game-over condition, then it's game-over."  Which is true, but it's also
pretty close to the canonical example of trivial.
