I am quite confused about this change of goals by dan too. It seems there are several issues that he tries to adress:

• ECAF under the current Constitution has no balancing moment, there is no election and arbitrators could not be removed from ECAF atm. (That could have been amended).
• Reversability of Transactions would also harm inter blockchain communication
• Current constitution is hihgly interpretable, thus can lead to unclear constitution.
• Regulations are unenforcable
  I personally do understand those reasons, but i think it would suffice to change them. Most importantly, the prevention of theft, has been one of the major selling points of EOS in the past month. Now that about to go is certainly a BP?
