You're misreading the comment. It's not that "for your safety" always implies tyranny, it's that tyrants always prefers to say that they're doing things for your safety.
Even that doesn't agree with reality. Some tyrants prefer to say they're doing things for your freedom, your money, or your rights. (In fact, you know what, it's silly to expect tyrants to stay consistent.)
It's well known that the TSA does jack-all for security. A "POSIWID" analysis reveals that its primary purpose is the normalization of tyranny in the broader public by ritual public humiliation.
To save someone a search: POSIWID = The purpose of a system is what it does
Others have already pointed out that the TSA is a joke, and US nuclear regulation is so dysfunctional that we've lost all ability to create new reactors, and it's setting back our ability to address global warming by decades.
Maybe OP means that tyranny tends to abuse the safety reasoning, not that all safety reasoning comes from tyrants.
OP said tyranny prefers to use safety as a façade, not that all safety is a façade for tyranny.
