If we are going to have a price stable currency, it should have price stability. Otherwise it's a failure.
But do we really need that? My opinion has been that it's great addition to ecosystem: people can build marketplaces. But so far we haven't seen any serious movement to that direction.
Another missing feature is privacy. People aren't going to buy and sell stuff with a currency of almost zero privacy. It's not even on a roadmap.
Right now SBD is beneficial to the ecosystem because there is so huge demand for a price stable cryptocurrency. But that might not be forever. In that case SBD might become an extra feature that's more of a nuisance than actual benefit. It just creates extra risks to the ecosystem.
But on the other hand, if we want to keep SBD, we have to find a way to create more of it to answer the market demand.
Another possibility, in addition to OP, would be to move to a Bitshares-like system. Just remove the liability from the blockchain and give it to the users.
