1. not. Sure. Hey. website.io is cool now. .ly too. But you don't know how long the rules will last. They may insist you must open a company in this jurisdiction!

2, "You can sue to have a domain name confiscated if you own the trademark with the same name"

Yes sure. What do you know about trademark law and English common law? A few hints: trademarks are granted for classes and a trademark in another class or another jurisdiction would buy you nothing. lets take sampleword.com

A trademark for sampleword for delivering consulting services would not prevent me from running a shoe shop under this domain. Or a trademark in the US would not prevent me from using in in another country. Country specific domains may offer some protection here but not for .com .net

Nobody is going to ask you to open a company in the British Indian Ocean Territory. In fact I think the people involved would rather you forgot all about it.

You don't know that. Rules can change. Would be a great way to bring money in.
