It happens for random, unjustified reasons. Wouldn't you want to protect your data from a country that behaves like that? I sure would.

Not using gmail doesn't solve that. If you cross a border you can have your device searched and denied entry if you don't cooperate. If you post on social media, the data is in plaintext for the world to see.

Are you trying to say that you don't need privacy because what you say publicly is public?

I'm not following.

If you say things publicly you have already chosen not to have privacy with regard to those statements.

Sure. And if you say things privately you have chosen to have privacy. Which is very limited if you say your private things on a US service and don't feel like having the US randomly read them and deport you.

That was my point, I'm happy to see that we agree :-).

You are misinformed as to the circumstances of the above stories you cited, because that isn't what happened in those situations.
