I dont think it is. Democracy does not rely on consensus, instead the majority rules over the minority. Bitcoin is a consensus. If 49% disagree, they can leave and create a second consensus among themselves, and this action does not somehow burden the 51% or vice-versa. If instead the 51% in a democracy decides to tax the rest, they can't really escape it.
