@ckie See, at that point I might as well have a dead enby's switch that releases an encrypted file that requires several people to come together to decrypt it via some secret sharing scheme...
But yes, I was thinking of this being a thing I would give to a person I trust not to abuse it in some way. The plastic is more of a thing for them, rather than against them. As in, they don't have to worry about it normally, but have my implicit permission to use it if they really have to. But, like I said, it's hypothetical, because I don't have people like that.
Also, you can find my birth name if you look with a moderate amount of effort, so it's not a terrible secret.
