This is not about trust for this key -- it is about validity.

The point is that the key does not have a valid binding to its User ID,
so encrypting "to the User ID" isn't going to work without prompting.

If the User ID + Key have been certified by some third party whose
certifications you're happy to rely on (and whose key already has a
valid binding to its user ID), you should mark that third party as fully
trusted.  Then their certifications will be acceptable, and the target
key will have a valid binding to its User ID.

Note that you'll need at least one key in your keyring to be marked as
"ultimate" ownertrust, in order to get the chain started someplace.
Usually, you'd mark your own key with ultimate ownertrust, since
(presumably) you know for sure which key is yours.
