That's not indication of presence. You can do that from across the border.
X does have presence in the EU, but it's because they have offices/employees, equipment, and accounts housed there.
The EU may say anyone who deals in the data of their citizens is subject to their jurisdiction, but enforcement on those entities without actual presence will be difficult.

Not particularly difficult.
Like Brasil already did, and for similar reasons, the EU can go after everything Musk owns. Even with Tesla sales dropping, they're not zero. Starlink is currently available.
