This is a fucking terrible take.
Obama was already elected and given the power to fill SCOTUS seats.
It's also totally legal to just appoint a hundred justices to the Supreme Court, since it has no limit on justices. The constraint of norms is meaningful and important, and lots of things you probably think are ironclad rest only on norms, so people need to take it seriously when those norms are violated. The country runs on them.
Haha if you want to break institutions court packing is definitely the way to go.
