They do, that’s why this is an issue in the first place. The purpose of ccTLDs is to host domains associated with a particular country. If the country stops existing, there’s no reason to use that country’s ccTLD. The problem is they let anyone register domains under this ccTLD even if they have no association with that country, hence the situation we’re in.

Some amount of organization is a good thing for many reasons. Think of an analogy to roads where basic traffic rules allow everyone the freedom to travel wherever and however but subject to the rules of locales. Feel free to pick your own domain within any generally recognized top level domain, according to the rules established by that tld.

In particular, two character top level domains are reserved for ownership by specific countries. They get to say who can have a presence there, under what standards, and they deserve any profit made from that. This was a way of giving everyone a voice, to expand it beyond the us, to give many interests their own home
