(In case it isn't obvious: I'm not a lawyer, I've not really considered this in any depth beyond some other news sources besides this tweet, and this is a totally noob question that may have an answer in literally lawschool 101).

AFAICT, Starlink complies with local regulations in the countries it operates in, including blocking access to specific IP prefixes and/or declining to default resolve DNS entries for specific domains.
IANAL but I'm pretty sure this is legal ground enough (plus all the shit Musk spits on Twitter, attacking Brazil and its institutions, a criminal offense in Brazil, from his ivory tower in Texas) to solicit a block of Starlink Holdings assets.
There are plenty of reasons out there to justify these actions and you can be sure Moraes will find them.
EDIT: Musk said this in April during Twitter Files Brazil.
Source? That's super material (if true).
I personally observe some of his viral tweet to be deleted later multiple times.
At some point I had a burst of motivation to start writing a bot to keep track of all the stuff he deleted for people like you to observe, but was quickly disgusted to waste any time to be on top of the argument with some stranger.
So yeah, without google or other search engine's ability to index the whole twitter, everything is written there is hearsay I guess.
The judge doing this may be, or may not be, as authoritianism is neither necessary nor sufficient as a cause nor this result as a consequence.

Basically a wilful misconduct.
However the balance of powers in Brazil are different from common law, or are corrupted, so we see what comes out of this.
From where I'm standing, this is legal security - not the opposite. In fact, I don't know if the law would allow it, but morally I would be fine with Musk being given a prison order or other sanctions for using such artifices in an attempt to evade justice.
The only time they tried to do tracking on where these posts and sockpuppets were coming from, they ended up in Israel (this is a common practice, I'm assuming to make tracing and legal action more difficult. In Portugal the bots come from Angola).
Its clear that the same disinformation farms that are running in the US were duplicated to Brazil, by the same people (Bob Mercer / Steve Bannon). Proof of that was of course, the deeply personal relationship between Bannon and the Bolsonaro family (when he was out of jail he would visit all the time), and the faux January 6th that was replicated in Brazil after Bolsonaro's defeat.
You have to understand that the population of Brazil has A LOT less education than the population in the US or Europe. They are far more malleable to disinformation.
One of the worse examples I can think of is the disinformation campaign that was activated after the murder of Marielle Franco, who was tagged in fake photos with local Rio drug dealers - while she was still dead inside her car. So a few minutes after the murder, you had a giant disinformation campaign launched. Since it was so fast, the only reasonable conclusion is the murderers control a disinformation bot/sockpuppet farm.
He owns 42% share. What about the other owners who hold the other 58%? What have they done to deserve their assets seized?
I can't speak to SpaceX shareholders because they are private, but of the public Tesla that's also associated with Musk, there are shareholders who want him out because his public behaviour is interfering with the business interests, and that argument will gain weight as a result of stuff like this.
Is that "deserved" depends a great deal about how you model the entire world, but activists investors are a thing and they do fight company management.
Merely having no office in some country not sufficient, for the same reason it wasn't sufficient for preventing New Zealand based Kim Dotcom to be prosecuted (and his Hong Kong-based Mega Upload domain to be seized) by the USA.
Or how X sued Media Matters in Texas before X moved there and despite Media Matters not being based there: https://www.threads.net/@sherrilynifill/post/Cz5Im7VONzd
Or all the defamation suits against US citizens filed in the UK on the grounds that being published on the internet counted as if it was published in the UK, forcing the US (Federal and State) to pass laws preventing payment of penalties in such cases: https://en.wikipedia.org/wiki/Libel_tourism
Edit:
Just found an interesting claim, thought I cannot verify it myself:
"Notably, Brazilian law necessitates all internet businesses to have a legal representative in the country who is authorised to receive judicial orders and respond legally." - https://www.opindia.com/2024/08/moraes-is-the-dictator-of-br...
and
"Under Brazilian law, social networks must have a representative to receive and consider government takedown notices about political misinformation. X has no such person after closing down its Brazil office. Moraes gave the X platform 24 hours to name a new legal representative or face a nationwide suspension." - https://www.siliconrepublic.com/business/x-brazil-suspension...
