You can't have a decentralised oligarchy, it's self-contradictory. Users won't support a system that doesn't support them and your chain won't survive economically without users. Network effects have a tremendous impact on value and utility. How do you propose your 0.5.4 chain will amass value and utility if only a few zealous cultists are using it? Keep dreaming.
Oligarchy don't need free users. They only need poor slaves.
