This is such a pretentious post. Firstly, stop acting like the world is only made up of developed nations. There are billions of people out there in territories that don't have such infrastructure, or that simply don't have access to online (servicemen, army, navy etc).
Secondly, designing a console that can't function with both groups in mind is just plain bad design. You can have all the functionality you originally wanted for an online only console, whilst also providing the same original functionality for people that don't, instead of just limiting or cutting off their gaming options altogether. That's not to say any of the functionality Microsoft was offering in order to promote an always online console was even particularly forward thinking, simply put, it wasn't. Family sharing turned out to be little more than a demoing scheme, and that was the number one key selling point for the horrible policy. The best way for Microsoft to prove otherwise is to simply bring back the game sharing policy for digitally sold games. There's simply no reason why they can't have it in with the same restrictions.
Add to that, Microsoft also claimed that it expected 1 billion (yes 1 billion) console sales (assuming across PS4, Wii U and XO) this generation. Such figures are an absolute pipe dream without a console that could function offline as well as online. To be fair, they're an absolute pipe dream no matter what.
In 2013, statistically 61% of the world is not connected to or not using the internet.
