I understand where you’re coming from, but in my experience, “Do-ocracy” implies a kind of passive consensus mechanism. Let’s say we all have collective ownership of a garden, and it’s starting to need weeding, but nobody’s taken the initiative to fix it yet. In do-ocratic fashion, someone announces that this coming Sunday is Weeding Party day, and that catalyzes action.
It’s tricky. “Weeding Party Day” will succeed if everyone has been made to see this is desirable, and if the person has charisma or a track record or seems well organized. But it’s a dance between collective will and individual will.
With “bulldozery” I think Vitalik is describing an extreme case where some entity is completely unfettered. A dictator decides it’s Weeding Party day, or an all-powerful council, or even a single individual goes and pays for a weeding crew and reaps the rewards themselves. So at this extreme point we find everything from The Great Leap Forward to the enclosure of the commons by capitalists or the seizing of lands by colonists.
Action and will for its own sake have long been associated with fascism; many people long for a strongman to clear away all the objections to “greatness”. But the tendency exists in all kinds of people, I think, it’s just that their desires for sweeping reform aren’t as violent.
