Apparently you havn't heard of EIP's, or any of the other approaches to on-chain governance. You are the one with your head in the sand. (pun intended)

Such an original concept that was borrowed from bitcoin. Perhaps you’re aware that the word “bitcoin” is referenced close to 90 times in the Ethereum whitepaper. Unfortunately, ETH cannot be improved as it was fundamentally flawed from the start.

There’s a reason you don’t often hear bitcoiners use the word “governance.” Bitcoin’s monetary policy and incentive structure is so transparent and predictable that it’s not necessary to continually tweak and devise new mechanisms to keep it from collapsing.
