It is obvious to me that the OP has missed a
major piece of the puzzle.
It's not just cryptocurrency that is making all of these changes... It is
decentralization itself that is... And those changes will be far, far larger than monetary.
Decentralization is nothing less than the removal of power from those who have it and scattering it around to all that want it.
Gnutella was technically the first decentralized program. (That I know of.) They may have fizzled, but today we have Bittorrent, Mega, and TOR, among others, to share information through. Together these make IP laws start to seem kinda silly.
Bitcoin is a bigger jump, because it represents half the economy; any product or service that someone wants to sell, worldwide, we can now buy in a decentralized way. But it's just the buying half...
3D Printing using DEFCAD search and the resulting industry built around downloadable products will represent an even larger jump... They are the other half of the economy, and everything one could sell will eventually be manufactured and sold this way. (Destroying pretty much all existing industry worldwide.)
But that's not all! What else can we decentralize?
Well, if the government does it today, why can't we decentralize that too?
Security? But of course. Why use the .govs police when you can have free-market security services bought and sold in a decentralized environment?
Law? No problem. There are already websites like judge.me that offer non-nationalized law... Making those into a decentralized solution would be childsplay.
Whenever you think it can't be decentralized, trust me, it can. Even
roads can be built privately, and decentralized marketplaces can expedite them.
Fire services? Same as security. It can all be done without any government once the interest to do so is there.
So I submit that bitcoin's influence on our future is one of many 'decentralizers.' -And not the largest one by far.
One much more likely outcome is that US government will pass a bill to have full and unrestricted access to ISP traffic, outlaw peer-to-peer technology and cryptography in all forms, and crack down on anyone they catch using cryptography and / or peer-to-peer technology.
So I guess you haven't heard yet that you don't have to use their internet?
We'll all be our own ISPs in a few short years. Wireless Mesh networking is real tech and they've even had it in the One-Laptop-Per-Child computers for several years now.
The range of wifi has been the largest stumbling block, however we are only 1 wifi standard away from having complete and total wireless freedom without any centralized points in it that governments can control.
