The filibuster has not lead to a centrist bill or confirmation in decades. It has led to the side willing to play hardball (read: the Republicans) getting their way.
If Reid had not done away with the filibuster for SCOTUS appointments, we would be sitting with a 9 - 0 ideological «split». Republicans would never have allowed a single «liberal» to be confirmed and would have waited until they had a Republican president before filling any vacancies. If anyone has any doubt, I give you Gorsuch and Barrett.
The Congress in general and the Senate in particular are are not the same as they were when we were children. One party has embraced maximalism to its upmost, even stating multiple times they they will never compromise with the Devil, i.e. liberals.
To keep pretending that nothing has changed in 60 years and to keep on operating as if all the old rules and procedures still apply is a sure recipe for ruin.
Everything is always changing. Adapt or die.
