I get your point and understand there are downsides. But do lifetime appointment SC judges get washed out in the next blue/red wave? They don't. If every President were guaranteed let's say 2 appointments to the bench with the oldest serving members being retired then at least we can maintain some sense that the makeup of the court matches, to some extend, the current will of the people (in an indirect way). Can the same be said now, even remotely? I don't think so. Right now it's a crap shoot (fuck you cancer!) but the GOP has figured out how to game the system better by nominating and getting seated much younger SC judges who will be in place for decades. If the only Dem response is to do the same then we have a race to the bottom to nominate the least qualified, ideologically pure candidates who a given side (Dem or GOP) thinks will toe the line for a few decades to come. I'm not sure how that makes for a better outcome for the country.
