This is a very naive argument. It assumes that other civilizations will be the same way al life on planet Earth. However, there is strong argument that evolution works in a certain way towards similar goal. Once sapience is achieved there is a very short path towards AI and existential collapse at which civilization cease to exist the way we see it now. After that it is unlikely to want to communicate to you or fight with you or whatever. At the same time evolution towards life is somewhat embedded in physics of our reality. So it's more likely that civilizations are abundant throughout the universe although it's unlikely we find any during extremely brief span of existence of our own civilization.
