When people get excited about something, they will often talk about it in hyberbolic terms. Some people will actually believe what they say, though this seems to drop off with age. The emotionally energetic framing of the point can be both factually wrong and contain a kernel of truth.
This general truth applies to hype about particular technologies. Does it apply to blockchain technologies and cryptocurrencies? Sure it does!
Blockchain boosters have offered utopian or radical visions about what this technology can achieve. We should be skeptical about these visions prima facie precisely in proportion to how utopian and radical they are. But that doesn’t mean that this technology isn’t accomplishing anything new or interesting.
Here is a summary of some dialectics around blockchain technology:
A: “Blockchains allow for fully decentralized, distributed, and anonymous applications. These can operate outside of the control of the law, and that’s exciting because it’s a new frontier of options!”
B1: “Blockchain technology isn’t really decentralized, distributed, or anonymous. It’s centralizing its own power into the hands of the few, and meanwhile traditional institutions have the power to crush it. Their anarchist mentality is naive and short-sighted.”
B2: “Blockchain technology enthusiasts will soon discover that they actually want all the legal institutions they designed their systems to escape. Their anarchist mentality is naive and short-sighted.”
While B1 and B2 are both critical of blockchain technology and see A as naive, it’s important to realize that they believe A is naive for contradictory reasons. B1 is arguing that it does not accomplish what it was purportedly designed to do, which is provide a foundation of distributed, autonomous systems that’s free from internal and external tyranny. B2 is arguing that nobody actually wants to be free of these kinds of tyrannies.
These are conservative attitudes that we would expect from conservative (in the sense of conservation, or “inhibiting change”) voices in society. These are probably demographically different people from person A. And this makes all the difference.
If what differentiates people is their relationship to different kinds of social institutions or capital (in the Bourdieusian sense), then it would be natural for some people to be incumbents in old institutions who would argue for their preservation and others to be willing to “exit” older institutions and join new ones. However imperfect the affordances of blockchain technology may be, they are different affordances than those of other technologies, and so they promise the possibility of new kinds of institutions with an alternative information and communications substrate.
It may well be that the pioneers in the new substrate will find that they have political problems of their own and need to reinvent some of the societal controls that they were escaping. But the difference will be that in the old system, the pioneers were relative outsiders, whereas in the new system, they will be incumbents.
The social value of blockchain technology therefore comes in two waves. The first wave is the value it provides to early adopters who use it instead of other institutions that were failing them. These people have made the choice to invest in something new because the old options were not good enough for them. We can celebrate their successes as people who have invented quite literally a new form of social capital, quite possibly literally a new form of wealth. When a small group of people create a lot of new wealth this almost immediately creates a lot of resentment from others who did not get in on it.
But there’s a secondary social value to the creation of actually existing alternative institutions and forms of capital (which are in a sense the same thing). This is the value of competition. The marginal person, who can choose how to invest themselves, can exit from one failing institution to a fresh new one if they believe it’s worth the risk. When an alternative increases the amount of exit potential in society, that increases the competitive pressure on institutions to perform. That should benefit even those with low mobility.
So, in conclusion, blockchain technology is good because it increases institutional competition. At the end of the day that reduces the power of entrenched incumbents to collect rents and gives everybody else more flexibility.
