One philosophical problem I see is the official position of Steemit Inc. as put in the whitepaper [august 2017 version), page 15/32: "Eliminating 'abuse' is not possible and shouldn't be the goal".
Maybe eliminating abuse is indeed not possible but openly stating "shouldn't be the goal" is deeply mistaken in my opinion. It is like saying "completely eliminating crime is not possible ... and so the police is useless, let's disband it ..."
