What? Ownership/power is distributed among all the miners, albeit a number much bigger than 7. It still exists and can (and will eventually) be consolidated by a majority cartel.
The article is correct about ENS, but implying that N=1000000 power shares (approx # of Bitcoin mining individuals, likely trending down as mining margins decrease) is different than N=7 power shares (ENS sigs) in the realm of security guarantees is just smoke and mirrors. Neither system abolishes power nor is immune to manipulation.
