you cannot really compare a citizen to a shareholder (if you cannot sell it, you dont own it)

    1- not all shareholders have votes 
    2- as a shareholder your vote is proportional to your owner ship
    3- you can sell your shares, you cannot sell your rights of citizenship .. to another immigrants for example 

they are not the same .. they are just not .. maybe on the surface from far far away they look the same .. to you

maybe as a citizen it feels good to think you own your country, but you dont .. really you dont
