Fortunately for the rest of the world it's illegal for the same reason google isn't allowed to pay your salary in google bux, and facebook isn't allowed to pay your salary in facebux.
Good thing there's stuff like laws people much smarter than you happened to enact before you were born so you didn't grow up one day and soil yourselves while they retired.
Cryptocurrency isn't going to the masses. It's going to broke AF basement dwelling creeps who don't realize that there's still a world going on outside of the internet, where most of the people are.
There are more than 3 billion people on the internet. The main reason the other 4 billion people aren't on the internet is poverty. While there will always be a world outside of the internet, you'll be kidding yourself if you think that brick and mortar stores are going to outcompete the likes of Amazon.com and other ecommerce platforms.

I don't think that these 4 billion people living in poverty are there because amazon didn't give them a good deal on shea butter and charcoal filters, and that they have no way to settle their debts without an ecommerce platform.
They need what the rest of the world has right now - a fully funded debt fueled top down controlled government structure that isn't constantly being destabilized with the full force of a military that is actually strong enough to decimate public uprisings. Or the technology to cause them from not happening to begin with.
Not some seeds, dreams and a belly rub. Not moon rockets.
No it won't be brick and mortar, but composites printed from the front of the welfare line that gets them in order. And it won't be blockchain technology they pay in, because they won't have any need for money. Commerce will be something that gets phased out anyways, and as you've already pointed out, doesn't even currently exist for over half the people on the planet.
Can't need what you never lost to begin with, right?
I agree that BTC in its current form is not the answer for hundreds of millions of people living on < $2/day in wages. However, BTC will change, evolve and may ultimately play a major role in democratizing access to finance with any mobile device (not just smart phones).
As far as ecommerce going away, I think you've drank a bit too deep from the Star Trek koolaid. I don't see this happening anytime before AI takes over, becomes a hive-mind and then there's no personal need to allocate resources or services. Short of this, even AI devices need electricity, maintenance, raw materials, etc.
As an example, take a look through the comments here: http://entertainment.slashdot.org/story/15/10/12/006239/can-star-treks-world-with-no-money-work-in-real-life
Always drink extra deep from the kool aid. If it's anything non toxic they'll just call you greedy and you can carry on to the next cult.
I don't believe that finance can be democratized any more than I believe these 4 billion people need anything from the other 3 at all, but were moving a bit far away from whether or not companies should issue funbux.
As far as maintaining the illusion of choice in a post scarcity economy - there's 7000 alt coins. Infinite horizontal value scaling has brought no real value to this. Yet the hivemind continues to follow the value over and over again. These people rarely invest in value, they invest in the illusion of choice, and sometimes by random chance or manipulation by those who see that that's what these people follow, they make a dollar or two.
But the value is diminishing, because people are realizing that investing in random chance or manipulation is degenerate. The scammer can't make money if he's the only one playing the game. Btc won't evolve because its not something that can.
Ecommerce will, sure. But btc isn't fiat. Not just btc either. Every single crypto is a bitcoin as far as the rest of the world can tell.
Even if they hear about an altcoin, nobody's gonna fall for the 'new gold of the week' trick more than a few times.
Crypto is much easier to manipulate than fiat, so its much less suitable than fiat to hold value, and as such, all crypto tends to zero. And its not an implementation or design flaw, its something a little more close to home. For as long as crypto is in a parasitic relationship with a fiat denominated society, it will never be decentralized. If it's not decentralized, it can't hold more value than fiat.
This is why we don't use facebux, and this is why we don't use googlebux. How could you people forget that?
