We've had a similar discussion at my work. E-commerce that only ships to North America. So blocking anyone outside of that is an option.
Or I might try and put up Anubis only for them.

I got accidentally locked out from my server when I connected over Starlink that IP-maps to the US even though I was physically in Greece.
As a practical advice, I would use a blocklist for commerce websites, and allowlist for infra/personal.
In the end I found another online store, paid $74, and got the device. So the better store lost the sale due to blocking non-US orders.
I don't know how much of a corner case this is.
I'm not saying don't block, just saying be aware of the unintended blocks and weigh them.
