We're already on the edge of point to point communication without radio waves so within another 50-100 years nobody will detect us either.

We're simply asking the wrong questions. Years ago I remember someone postulating the idea that if another civilization wanted to be found by another civilization, what they would do is find some interesting stellar object, and embed a signal in whatever radiation it was emitting.
So, another civilization would have to be a) capable of recognizing that object as interesting, b) have the capability and will to study it, and c) detect and separate a signal from the background.
The "You must be this tall to ride this ride" theory of interstellar communication.
Communication through entanglement still requires transmitting all the information you are trying to communicate through a physical communication channel like radio or some other channel like lasers or whathaveyou. The only supposed "benefit" of the communication is that it prevents undetected eavesdropping. Although, that's hardly even a great benefit, because you want to prevent eavesdropping, not just detect it, because that means the presence of an eavesdropper would kill all communication. There is thus not even a practical security benefit for communication through entanglement. It's largely overhyped. May have some niche use cases but not anything revolutionary.
