I don't need to send money to the other side of the world in a decentralized way. There's a good chance I never will and similarly 99% of people do not and never will have this problem.
There are at least a dozen countries that I can think of that have massive restrictions on how many flows in and out of the country, preventing people from being able to keep their money safe from raging dictators or changing rulers.
It's a lot more than 1%.
Obviously providing some service to even .01% of people or whatever is valuable. But at this point Bitcoin is valued like Google which is used by tens of percents of all people.
