I understand where you are coming from . However there is a  flip side of  activist courts who base their decisions on supposed  penumbras and ethers of the Constitution and who have usurped many executive and legislative branch powers over the years. This increase in the courts power is what makes any appointment to it so important and causes the over the top  political games we have seen in the last 30 years in regards to appointments. It also increases the partisanship within the court. I really think it is time to consider limiting SCOTUS appointments to 10 years. Lifetime appointments for what has become such a powerful position is too long. Of course that would take a constitutional amendment so is highly unlikely- though I think it might be something that might be attractive to folks wherever they are on the political spectrum.
