I would never design a crypto project wherein the individual users (aka the tyranny-of-the-mob) could vote or otherwise be involved in mutating the protocol. The users should only be able to enforce the protocol, and never mutate it. Because users are dumb and have many conflicting needs they want to meet, which may have nothing to do with objectivity, i.e. the reason democracy is a clusterfuck. Satoshi designed proof-of-work such that the miners and whales decide. Period.
