The role of the judicial can be fulfilled with lesser courts without the overreach provided by the SC; they’re meant to interpret and enforce, not invalidate.
You don’t need a lifetime appointment for a long term view of the law, it’s not as if politicians in other branches retire after their terms or don’t serve as many terms as possible. The possibility of churn is, in theory, meant to keep those branches beholden to their constituents. Even that’s often insufficient to prevent corruption, but at least it’s something.
