It's the ownly truly decentralised digital infastructure that we have.

If he was to build it on Ethereum and claim that it was decentralised, he would have been just as well to have Klaus Schwab code him something up, instead.

I think there's a paralell here with the argument around Bitcoins energy use...

Most bitcoiners make the case that using all of the electricity is worth it, because of the benefits truely hard money confers on society.

Equally, most bitcoiners make the case that 1 decentralised blockchain is enough.

By the same token, if the world is to have decentralised identity [and we can debate this, as a seperate issue], then perhaps the cost of a transaction or two, per block, is worth it....
