SP should be eliminated and Steem alone in the wallet can be used in a similar fashion as SP.

I've made this exact point repeatedly in various witness chats. It seems to me like a natural subject for the next fork post SMTs anyways. First to simplify things in the face of multiple new tokens that will otherwise be a mouthful for new users to wrap their heads around an already complicated platform. Second to judge whether or not inflation-derived rewards from stake-based voting should continue to exist on the main token once SMTs are here.

An ideal situation would look something like this: Steem Power and the STEEM savings account are both removed completely. You simply hold STEEM in your wallet. It can either be liquid (default) or locked for a specific time period. Carrying out actions that require the use of resource credits, or casting witness votes, will necessarily lock the required STEEM to be granted those resources, or the stake that you decide to support a witness with, for a given amount of time (to avoid abuse of resource credits by people who could otherwise swap STEEM from one account to another and take up the available bandwidth). Users can then also themselves lock their STEEM for any given amount of time specified by themselves as a means to add security.

This would simplify things by several orders of magnitude for any new user coming to Steem and wondering what they need to do in order to participate, and what is up with all these different names for basically the same token.. It would also allow for flexibility in terms of different users with a different wish for security versus liquidity being able to choose what they want without us needing to find a "middle ground" which in the end doesn't satisfy anyone.

Finally, we would not have this childish term "Steem Power", which may be cool for an SMT used in a gaming community, but isn't fit to describe the main resource powering an "enterprise-grade" blockchain.

Obviously, this requires a serious rework and a lot of discussions, which is why I believe it deserves its own fork rather than being lumped in with the long awaited SMT fork.
