I think you missed the point of the Wikipedia article. Structurelessness (and that is still what you're describing) leads to a tyranny where there are unspoken leaders who basically bully the rest of the organization. You described exactly that and then asked how to avoid it. Short answer: You probably can't. It's a human problem, not an organizational or process one.

Clear lines of ownership and responsibility do wonders for just letting coders code, and let everyone else decide what they code.

Exactly, it's "leaderless" in the same sense that a class of high schoolers is "leaderless."

No, I got that. The article also has the person who demonstrated it advocating for democratic control of leadership, and I was commenting on how that might run into its own troubles.
