It is questionable as to how people feel about current money. Kenneth Boulding has written a paper for Central Bank Board of Governors on the legitimacy of central banks. Towards the end of the paper, he states:
Insofar as the legitimacy of the central banks is enhanced by alliances, it is with the national state, and the national state alone. In these days the national state is so fantastically legitimate an institution that it seems almost absurd to suppose that its legitimacy might decline or even collapse. Nevertheless, stranger things have happened.
In fact, we would wonder just how stable the nation state is today. The Internet itself has challenged certain fundamentals and the questions continue to grow louder. And when it comes to central banking itself, the high level of inflation and control over the value of money influence money in ways that cryptocurrencies may not.
No one forces you to use cryptocurrencies right now, though you are forced to use national currencies to pay your taxes and the like. Over time people may gravitate to cryptocurrencies that are not so controlled. Just as they will be attracted to blockchain implementations that are the most free.
The problem with this is that the largest central and public banks might not let that happen. They could pass laws regulating what blockchain can and cannot do. And they will make it easy for them to be utilized in certain ways and not in others.
Thus people may go outside of government to use blockchain and cryptocurrencies on the gray and black market. It is not difficult to transact a cryptocurrency peer-to-peer. Nor is it difficult to use a freer version of blockchain than what central banks are building.
Government regulators may not be in favor of this, but it could happen nonetheless if regulations are too deep and make blockchain and cryptocurrencies much less usable than they should be. Regulation begins in the market itself with various implementations that make it possible for the markets and its products to become popular.
Secondary—government—regulation may not be nearly as necessary and is often intended for purposes of control rather than to make the market “safer." In fact, regulations are basically price fixes. Over time, price fixes are not efficient and rarely do what they are supposed to do.
There is also the question of middlemen and how blockchain, especially, will reduce middlemen, perhaps dramatically.
Solar Change is just one example of many that will reduce middlemen. Its Co-CEO is Assaf Ben-Or, a Ph.D. in Solar Energy and an experienced start up entrepreneur, with experience in blockchain, data security and renewable energy. The Solar Change platform is built from blockchain and helps increase the use of solar energy worldwide. It is increasingly taking aim at fossil fuels and those who run them.
