If you know that you don't have customers or users in the area, or very few, then go for it.
I worked in e-commerce previously, we reduce fraud to almost zero by banning non-local cards. It affected a few customers that had international credit cards, but not enough to justify dealing with the fraud. Sometimes you just need to limit your attack surface.
This is particularly annoying as knowing where people come from is important.
Its just another reason to give up making stuff, and give in to the FAANG and the AI enshittification.
