Well, the animating idea of modern democracies is that we do have input into governance. (Whether that's a foundational truism or a useful myth is a separate issue -- people are supposed to believe they have input, and most do believe that.) At least some of the difference between the governance of Portland versus Houston, or California versus Texas, or the USA versus the UK or Finland, is due to different preferences of the governed.

And, even ignoring formal political 'input' (or the simulacrum of same), we all make the culture and economy as neighbors and workers. When a smart, productive, and freedom-loving person with many options chooses to live closer to me, under the same standing rules, it's a positive indicator about my desirability as a neighbor and an external validator of choices I've made previously. Hence, 'pride'.

> to which you had no input

That depends. I assume you are the most google'able Mike from Bath Spa. I stayed in UK to finish Bath Uni, so lecturers from there could probably feel proud of creating an environment where I felt welcome enough to stay for a longer time. It was their input into my environment and education and it did make a difference, because I still live in Bath.

Then again, this would be a personal situation and not "I feel proud, because some known guy wants to live in my country".
