The idiotic statement is yours. If the "sometimes" is important to you, you can have it - you're not the first person on the internet to play word games.
But unless you can come up with a very detailed list of when it's acceptable "to lock people down and physically prevent them from harming themselves" and when it's not acceptable (it never is, it's a crazy statement), and I don't think you have such a list, your "sometimes" just means "whenever I, as the person writing the software judge", rendering it completely meaningless.
> We have to lock people down and physically prevent them from harming themselves.
You can apply this argument to literally anything, and taken to its logical conclusion, this is exactly what will happen.
