I find it interesting the concept you lay out above. I am sceptical though whether it should be labeled a "Constitution". I prefer to make decisions on principles that I find relevant to the subject in question, whatever that might be. Regardless of the fact those principles exist in a published text or not, aiming to mould the users' expectations, according to individual interpretations.
After all, Constitutions are ever subject to abuse. Whether the decisions are valued as right or wrong is reflected upon the value, the users assembling the market signal through price mechanisms. In that case ofcourse the "whales' " role is a matter of further investigation, but in the long term their actions are countered by the majority microholders'. #AndreyNikolaevichKolmogorov
