The thing with not every country agreeing can be solved by cutting the countries economy off of the other countries. For example if all of the eu would do this if you hava an eu company you can just function normally inside the eu but if you youre outside the eu you have to take a lot of steps to start doing business that assure that you dont ransack the eu. Idk if something likenl this works but this is the best i could come up with.
