The problem is the filibuster is a choice of the senate. They can at any time decide to do away with it, it’s not law and not a law of nature. But they don’t because it serves their interests to be able to throw their hands up in the air and not even have to try to pass legislation.
That's no something that is going to happen, -both- parties dearly love the filibuster, if it can just be done away with, against, precedence then it will become useless whenever a party gets the slimmest of majorities. I'm not sure how much longer it matters though, if this turns into a dictatorship
