I understand your perspective and it holds water too. Though, most people who are advocating your position to retain SBD in the comments are expressing STEEM's volatility to be a significant cause for its difficulty with new users.
@thecryptofiend's comment below does an excellent job of delineating the role that SBD plays in that volatility. Should SBD be removed from the equation, then we may very well see the price of STEEM stabilizing, negating at least one of the complexities of STEEM for new users.
