About those benefits of having a US passport, could you mention a few of them? Because I'm a US expat and wondering why I have to keep filing tax returns but receive no benefits whatsoever. A number of important examples:

Being a non-citizen in the country I live means I am at the end of the queue for vaccination, while the US State Dept says it won't arrange for vaccinations of US expats, but countries like France and China are doing it for their citizens.

I can't maintain a bank account in the US because without a US mailing address the banks simply refuse to provide me services. The US government could care less, has no requirement that banks provide services to US citizens overseas.

I'd consider the services provided by the US Department of State and the US Military to have some value for American expats.
