Not fully block / null-route of course. You might however consider to
not allow ssh-logins from certain countries (if you know what you're
doing) to avoid noise in the logs, might monitor incoming emails with
smtp-auth for suspicious activity based on country (of course there can
always be someone on holiday in those countries) etc.

All I'm saying is that attacks or spam sometimes seem to originate
mainly from "certain" countries. Judge for yourself what you maybe want
to use that additional piece of information (geo-location) for - and use
it wisely.

Kind regards,
