I don't think the complaint is about the lack of new ideas for coins. No shortage there. There have been a lot of prototypes, trials, testing, and scams, but not a lot of hits. The only major exceptions are the same old cryptocurrencies (Bitcoin and Ethereum) where the same old arguments still apply. Part of the problem here is that, with no centralized authority, it takes much, much longer to make changes. Perhaps that's what the author is missing and that's why we're many years in without the kind of success you might expect for a web technology that's not destined for failure.
