Once again, you have ignored what I said.

If you have a game that's available in multiple regions published by different companies, then the "playable game" will start competing with the still published game in other regions.

This creates financial risk for the developer of the game (in the original region). They might be better off not releasing the game in the US/EU to avoid this risk. Many KR and CN games already don't release globally or it's done as some kind of afterthought.
