It's not quite the same: in cryptocurrency even stakers/miners cannot break or manipulate the consensus rules themselves. They only really have power in a small number of decisions (most significant is the power to censor transactions in a 51% attack). This is not the same as existing financial institutions where the powers that be have in principle much more power. In practice the main power associated with the community is in those voices which are most heard: this correlates with wealth but not necessarily strongly. These are the ones who have most power over what consensus rules are used (much like in democracy).
