These distinctions are only as arbitrary as the law, which can be very arbitrary but ultimately we have agreed to accept the Rule of Law, both my country and most likely yours.
Nations have agreed to fairly consistent diplomatic protocols and channels with which to treat each other. Hawaii can’t issue visas, but Japan can require Americans to apply for a visa. That isn’t just a stretch of the Commerce Clause, it is part of how and why the US Constitution was written the way it was: so individual States weren’t forming international interests contrary to the national interest.
Case in point: I have an EU driver's license. It is valid in the EU. When in the US, driver's licenses are per-state, though I am allowed to drive in a different state for a while, I have to get the current state's license when I move my residence. California has border checks for agricultural goods. etc. etc.
