It seems at this point that any aspect of the Great Filter that is from planet formation must be declared to be completely negligible. Is this analysis accurate?
I am not an astrophysicist, so not an authoritative voice here, but yes, almost every star is likely to contain a bunch of planets, some probably in an inhabitable zone. Even our close neighbors, the three Centauri stars and Vega have planets around them, or at least an asteroid belt hinting at planets. So, at least a couple of terms in the Drake equation are very close to unity.
