I mostly agree with this but more than shorter code I value readability, I would rather take 3 lines to be clear to any developer than use some obscure or easy to misunderstand structure to write it in 1.

Not really a problem for me, I try to be empathetic towards other people though!

OK and what are they? Having dual nationality makes it easier to travel. For example there are countries where travel or visiting for more than a short period is very difficult for non citizens, if you emigrate from said countries but you need to return for an extended period (such as family illness) you need to keep citizenship to be able to do so legally.

So just a gut reaction? Cool.

There are plenty of good reasons to have dual nationality.

Why not?
