The author is Craig Wright. Wait a minute?! Isn't that the guy who invented bitcoin? Isn't that Satoshi?
lol
Maybe. Afaik Satoshi was always in favor of scaling up the block size as the numbers of transactions increase. Getting rid of the signature block via Segwit is just "proof by Authority" and doesn't really solve anything since you'll eventually need to scale up the block size anyway as Bitcoin becomes more and more popular.
The network as Satoshi knew it is very different from what it has become. I don't even think he took into account that nodes could be specialized and not do any mining? Otherwise he would have looked for a financial incentive for nodes, which is notably absent now. If nodes were paid for their job their would be no problem with increasing the block size, but because they aren't the security of the network would be greatly put at risk.
