There should be some form of recourse for the Federal government to seize everything you own if you spread misinformation about a disaster and potentially impede the actual response.

I can think of a few appropriate ones!

This is exactly why Musk bought Twitter.

NatSec laws exist

“Are you saying this man and hundreds of others are all lying?” …yes?

In addition to asset seizure I would like to also propose the following as a possible solution

I'm all in favor of a Fed agency seizing Starlink, fuck that scum bag Nazi fuck.

i find it utterly impossible to believe that there's no one within the federal apparatus sitting on buckets and buckets of dirt that they could threaten him with dumping on the table if they wanted to

Oh, hey, it's that guy that caused chaos during the Maui fires recovery efforts.

There's actual no shit SAR going on right now, and the richest man in the world getting in the way of that should at minimum allow the FCC to block his ability to communicate.

This is all happening on the ground fast - how do you know it's misinformation?
