What guarantee is there that .com is an international company, .co.uk is a British one, .org is a non-profit organisation? Zero. (The only exceptions I can think of are .police.uk, .museum.uk and possibly the almost-entirely-unused .ltd.uk - even .gov.uk is full of junk)
All the TLD's are a waste of time, because it's first-come, first-served and anyone from any country can take them. So you can be pipped to the post to them by, quite literally, anyone in the world with the vaguest resemblance of a right to the name. Pharmaceutical companies threw a fit over their TLDs because of this.
In a world where we can't even agree who owns the Scrabble or Monopoly games, and things get accidentally released in the wrong regions, revoked, and you can't buy a particular game because it's "not the EU version", you have no hope in hell of limiting a TLD like this.
