Just take a look at all the discussion about increasing the block size limits ... a community just can't come to a consensus (ours included) .. you need voting by stake which inevitably makes a blockchain a DAC .. IMHO
Indeed, that is essential for the system health. However since Bitcoin has a userbase too big compared to other communities, that problem naturally scales too.
And I would see Bitcoiners completely against that because exchanges and mining operations would have the biggest voting power and manipulate it at will. Thing is, they already do.
