That’s why I hate the “give the government a master key” metaphor for weakening encryption. You aren’t making a master key, you’re making every lock worse. The “master key” is just knowing how to exploit the giant flaw you’ve now created in every lock, and if that knowledge escapes every lock is now worthless.
Knocking “shave and a haircut” now opens every door, let’s hope nobody else figures that out! I know! we’ll lock that information inside this “shave and a haircut” safe!
One thing I don’t like about the “master key” metaphor:
I do lockpicking as a hobby. And locks built for a master key are easier to pick, because you can open them with two keys. It seems kinda obvious when you think about it. (You gotta be careful when picking mastered locks though, the master wafers can fall into the keyway and permanently destroy the lock.)
Its like the old bank deposit zipper bags with the lock, turns out ( because its soft fabric ) you can just push the fabric through the zipper and balloon out the sides that have passed through the zip/lock, and dump out the contents.

TSA luggage keys are a good counter example.
In theory, only you and airport security can open your case. In practice, you can pick them up off eBay for next to nothing.
