You've nerd sniped me!
No country is going to force their big multinationals to change their international name they chose back in the 50s and are now known as world-wide. Personal names aren't too chaotic either, as the choice presented when choosing a romanization is limited, people can't just make stuff up on the ground. They're off, but generally in the same ways.
> Nobody wants to be called Mr. I, O, U, An, or No.
An is pretty common - given the massive reach of KPop among global youth, I wouldn't be surprised if the most well-known 안씨 as of 2025 was an "An" (a member of the group 아이브). Roh has fallen out of favor, young 노s generally go with Noh, the Rohs are usually older people. I too do long for the day where an 이 or 우 just goes with I or U, or if they must, at least Ih or Uh :)
IMO you left out the worst offender, Park. At least with 이 or 우 I can see why people would be hesitant to go the proper route, as most of the world is unfamiliar with single-phoneme names, but 박s have no excuse.
With 이, there's a pretty good alternative as well, and what's more - it's actually already in use when talking about the greatest Korean in history, Yi Sun-Shin! So much better than "Lee".
