Well sure, if you are incredibly lucky and already own your core brand in .COM, then maybe not, but that's an extremely rare occurrence, and even then, I don't think you want your ccTLD owned by anyone else, if only because Google gives true ccTLDs a nice local bump in the search results.
And bringing up an ultra-expensive, pronounceable LLL.com like BOL.com as an example of why you don't need a ccTLD is pretty zany. That's top-of-the-line right there, but it obviously represents a tiny percentage of NL companies.
It's similar to Canadian banks, which make billions a year and can easily afford premium domains like TD.com, BMO.com and RBC.com (with most also owning the .CA) but again, that represents a microscopic percentage of CA firms.
The only type that might be excluded are massive multinationals who own their core .COM brand, like Intel (who coincidentally owns Intel.us) or Walmart (who umm... also owns the .US), or Volkswagen (who owns VW.com, along with the .DE, .CA among others), or Sony (who own Sony.jp) or... wait, what were we talking about?
