I'm a PTS/AGS/BTS guy from way, way back . SBD is perhaps one of the best components of the Steem ecosystem. It needs to stay... but in my mind the biggest risk to Steem is that the anchoring store of value is tied to the FRN. This is not a good long term strategy for storing user's value as it puts all the eggs in one increasingly volatile basket. And... Trump.
My vote would be to go the other way - instead of reducing available assets in an effort to simply/boost pricing/whatever, pull the Bitshares DEX directly into the Steem ecosystem. Allow Steem users to store value in whatever way they choose via bitAssets. bitGOLD, bitSILVER, bitCNY, etc.
This will diversify the value contained within the Steem ecosystem and make the platform much more robust and resilient. The whole point of crypto is move away from the existing economic power structures - and tying Steem to the FRN is severely handicapping the ability to become a freestanding economy.
