I would say control is inherent with ownership.
To believe the narrative is otherwise is likely going to fail. The key is to decentralized the control. If anyone could run a mining right cost effectively and have a decent chance at getting a payout once in a while, then perhaps it could fly.
Since that isnt the case, we see the mining pools and what they want to do. Ownership means they control.
And now their master is becoming the likes of Blackrock.
