I’m really torn on this. If there is a massive increase in the volume of transactions on the Steem blockchain, SP might become very valuable, the fuel for in-demand Resource Credits. But for that to happen, blockchain volume would possibly/probably have to be several orders of magnitude greater than it is now. Steem Power has always been what someone (@oldtimer?) called The Holy Grail. Many of us here have worked to build our SP for the long haul. A move to SMT-only rewards has the potential to invalidate that strategy. Would only authors/curators no longer earn Steem? Would inflation be trimmed so that only witnesses, the DAO, and SP hodlers earned Steem? Or would one or more of those also no longer get the inflation? There are so many unknowns.
