OP here. I should not have used "Copernican Principle." I knew that was sloppy at the time. I wanted to use something that covered anti-human exceptionalism, except I don't know what other phrase that might be.

I totally get where you are coming from. The Rare Earth solution appears to be the answer to the Fermi Paradox. Is it really a paradox though? Maybe it was just naive to think that life should be common, because solar systems and planets are very plentiful.
