You know what, Biden should go on TV and say "if the Court is going to be reviewing so many administrative regulations, it's going to need to be a whole lot larger. Going to need *puts finger in the air* idk, 5 or 6 justices"
There is a genuinely good argument for that kind of restructuring. E.g. make SCOTUS a much larger pool of a dozen justices, with maybe 5 randomly selected justices sitting a panel for a given case. Gives them a whole lot more bandwidth and makes it much harder to game the courts.
