Your points are well taken. I doubt that the eosDAC team had the neighbor's analogy in mind during the development of the app :-). Since voting on custodians is one of the main functions of the site as of now I understand that they ask people to join the club first by signing the constitution. I have followed EOS closely earlier last year up until the launch and have not spent much time on it since. Now I am happy to see first Dapps evolving. IMO EOS is an interesting real-world experiment with voting, constitutions, arbitration.
