On the dangers of cryptocurrencies and the uselessness of blockchain
There are many flaws in this perspective, but I'll pick one: the argument that there is no problem being solved with blockchain. This is trivially falsifiable: blockchains are being used to facilitate illegal transactions.Of course, from there, people often wince. But that wincing comes from an assumption: that a transaction is morally just if and only if it is legal. This is a fairly bad assumption (particularly with a brief skim of the history of the 20th century), but even if it were true, it is provably the case that blockchain technology is solving this problem in a way previous solutions have not been able to, given it is the chosen mechanism.
