Since you asked for an opinion, here's mine.

There are people who are praising the English language for having two distinct words: "safety" and "security".
Other languages / cultures don't see the need to separate these two (German: Sicherheit, French: Securité, etc.).

- "safety without security" is not a thing
- "security without safety" may be a thing
