Can the SCOTUS undo DC statehood?

[Pericles]

Wasn’t it mentioned somewhere that statehood cannot be revoked for any state unless the state wanted that?

If the Court were to just straight-up find that the granting of statehood in & of itself was unconstitutional, then that would be the end of that, previous precedent be damned.

Isn’t unconstitutional to remove a state, or was that just a norm?

It is unconstitutional to remove a state if they are rightfully a state, but if they were never really a state in the first place their statehood could be revoked. Some really hardcore originalists have argued that West Virginia is not "really" a state, for instance.

Didn't Barrett herself basically say that, except for West Virginia she thinks its statehood is such a 'superprecedent' that the Court can't and shouldn't overturn it. A factor which wouldn't apply with DC statehood.
