Yes, that would be the case. It should be fairly safe to use a 12 byte
passphrase (96 bit key) with a modern symmetric encryption scheme, but
no public/private key system will be safe with such short key length.
But as Lenz pointed out, the key length would generally be 4096 bits,
which is impractical for a symmetric encryption key (since the user has
to type it out each time).
Furthermore, even with a 12 byte passphrase, it’s user generated, so
it’s unlikely to be truly random, which decrease the search space
So in practice, I think asymmetric encryption is the better/stronger
For the same reason, many servers do not allow password login but
require key exchange authentication because (user generated) passwords
