Unless you're the IRS.

Apply that line of thinking the other way around ("There is more to US citizenship than holding a passport"). Its horrible by implication.

I'd prefer if nationality was being seen as bureaucratic artifact and not having more meanings attributed to it.

Examples involve Marie Curie who fled to France, but is always considered Polish. Poland didn’t give her a chance to be recognized.

Generally speaking, I would also note that outside of the Americas jus soli isn’t the norm. In South Africa, jus soli is restricted to partial sanguinis laws where the parents of the individual concerned must be South African citizens or permanent residents.

Further, Elon has openly stated the aim to make humans multi-planet, holds multiple citizenships, and views government as a territorial monopoly on the initiation of violence. Based on these three things, I’d say he has little allegiance to any given country, and that he’s more of a nerd who just wants to do stuff without worrying about anything else.
