Great input.  Systems of currency have been around forever.  But I think the problem with them, in any implementation, is the reliance on and cost to humans in order to maintain the system. Technology has the means to remove human effort and error from the equation, it's mostly just a matter of proving the implementation (getting that trust level built up) and making the interface easier to use on day to day basis.

But, that will no doubt happen.  And as it does, I think we'll find people all around the world are wanting to participate in this global economy. With cheaper methods of creating,  storing, and transferring around our individual and cumulative value... I can see borders completely disappearing and an extreme change occurring across the globe.  There will still be bad actors, because that won't just disappear from the gene pool, but I think that we'll largely be able to transition society away from centralized governments and huge central corporations and instead govern ourselves with a truer form of democracy and in which everyone has a less costly and more rewarding experience.

A government that is not relied upon to operate and maintain every single aspect of our financial economy - and all of the rules and laws and wasted time and effort that goes along with trying to maintain that harmony - is one that can instead focus on what's more important to the people they're governing. This applies globally.

Blockchain should allow every level of society across the globe to operate at a fraction of what it costs today.  We should be entering an era of extreme abundance and one in which traditional economic warfare disappears and we instead pool our collective efforts to build up the neglected parts of the world so that they're able to participate in and enjoy the abundance as well.
