at one part of your OP you are talking with the mindset of a one world currency. which in and of itself is not a good thing. choice and freedom is better. so trying to force people to get the internet and then force them to use bitcoin wont work.

bitcoin is already 150 of 200 real currencies of the world based on market cap. and its achieving this not by becoming a dominent currency, not by becoming a government used currency(fiat). and not by using pressure.

for instance in africa the majority of their economy IS based on cellular phone access to funds (mpesa). so bitcoin can work even in third world countries

there are over 1 billion mobile broadband (3g/4g) connections in the world and 5 billion cell phones with active lines in the world.

there are over 3.1billion internet subscriptions

so try not to think that bitcoin only has usage to 1% of the world. it has potential of 50% of the world.
