The whole point of winning presidencies is to appoint justices when one retires or passes away.
Packing the court, i.e. expanding the court to obviate the need to wait for a justice to retire or die in order to appoint a new one, on the other hand, effectively eliminates the independence of the judiciary, by nullifying the independence that Supreme Court justices obtain as a result of their lifetime tenure.
