Fully agreed - and most blockchains have chosen "no consititution." And got into a mess because of it. One could also say that these experiments were just that - experiments to find out how far we can get without a constitution and what happens when something is needed. We can point to BIPs as examples of evolution in governance.

We can also design from the position of hindsight. And we can design to preserve the good while reducing the bad. That's what this series tries to do - hence the notion that we want a constitution that acts as a filtering device: "wot, you mean if I hack a contract and steal some money, it'll be clawed back? Nah, I'm going back to bitcoin where I can have more nefarious fun..."
