Presumably the idea is that fabricating a legal offense to shut down a ccTLD would be easier than it would be for regular TLDs.

I don't know if that's actually the case, I've heard some shady sites are using .su(Soviet Union) to avoid judicial actions.

Wait, we're talking about buying domain names right? Not about buying countries in order to own a ccTLD rather than a 'regular' TLD

So then you don't have to produce an offence that takes the TLD down (whichever kind) but one that makes a judge within the country that the TLD operator operates in approve a takedown notice for your domain name or even get the TLD operator to cooperate voluntarily
