Good luck with that. What happens when there’s a dispute with a Colombian entity who wants your domain? Who do you think will have the advantage? Would you trust the Colombian registry and courts to favor you?
They could take the dispute to the UN internet court for domain names, whatever it's called. I can't see why that would apply only to the TLDs that existed 20 years ago.
You’re thinking of WIPO, perhaps? IIUC, they can’t interfere in the affairs of a ccTLD registry unless invited to do so. So if the Colombian authorities says you lose your domain to some local Colombian outfit, then you lose.
I was thinking of WIPO, and that's interesting that they have to be invited. I guess someone could always establish a cheap LLC there if they really wanted protection.
