It look like physics.pop-ph is the new physics.gen-ph for low quality submissions.
Skimming the paper, it does not look promising either. Attempts at answering the Fermi Paradox often fails to meet the bar of science. It's impossible to estimate any of the parameters except for things which are approximated through observations, like the number of galaxies. Otherwise, predicting how many rocky bodies may have life, who knows. Or how many attain intelligent life.
