More realistically? Add more members to the Court so they're the majority and then overturn it.

This will at best take a LOT of time. Congress is not famous for their speed.

At the worst it is politically impossible.

So how is this realistic?

What you said first can probably be done, even if it does break the democratic norms. This latter option seems unrealistic to me.

Bare minimum Biden needs to declare a state of emergency, a Constitutional crisis, and talk to us on TV about what his administration is doing to handle the crisis firmly and expeditiously. Anything less is irresponsible.

The people in Biden's admin are smarter than myself. All my simpleminded self can think of is using the power of the official acts against the SCOTUS itself. If Biden's White House has better ideas, get on TV right now, and tell us what they are and what is the White House doing about SCOTUS and the nearly unlimited expansion of the presidential powers.

Pretending we aren't in a Constitutional crisis right now is political malpractice.

This isn't business as usual, President Biden.
