They are though, if bad == insecure. Customs can make you unlock with fingerprint or face. If you can't lock yourself out, it's not secure.
Because they fall in the category of "will be used" as opposed to perfect security, which almost always falls in the category "won't be used"
(a) the world was only US citizens.

Allow me to repeat myself,
If you can't lock yourself out, it's not secure.
For example, some banks have time locks. Nobody gets into the vault, unless it is in a certain window of time.
It's not secure if you can lock yourself out either.
A court could hold you in contempt for failing to unlock or intently locking.
And a state actor or even mugger could just hurt you or even kill you, in frustration if you don't open it for them.
