In retrospect, this is a bit extreme. Automating crypto is useful, but
only as secure as the data accessed by the automated process.
Automating the local use of a passphrase, though, is completely
self-defeating. Anyone who has access to the files used in automation
won't be prevented from getting *all* the information needed to get the
passphrase or its equivalent. Thus, the security of the passphrase is
null and the only security that has any effect is the security used for
access to the files in the first place.
Passphrases are meant to be kept in people's heads, not recorded for use
