Just think how the world would have been if citizenship was the same all over. That would definitely simplify a lot of things! I know my son in Ireland would have enjoyed it.
If citizenship were uniform globally, it could lead to greater mobility, reduced barriers to travel, and easier access to rights and resources. It might foster a stronger sense of global community, too. Umh... maybe something the world can learn from Steemit.(•ิ‿•ิ)
