Based on this post, apparently citizenship is also voluntary. You might say that giving up citizenship is difficult and expensive, but you should talk to someone who has gone through a divorce.

I would also counter that citizenship also almost always necessitates an emotional element. Citizenship is a primary part of many people's identity, and identity is the most emotionally charged thing of all.

Divorce might be expensive, but never getting married is cheep.
