RE: Single token, simplification?!
Your proposal is not simpler then the current state of affairs, one could argue that it has more cognitive load on end-users. I think that you are just expressing your desire to be able to sell quickly when the market goes bullish.
It is my opinion that DPOS governance works "better" when staking is used as the key that opens the voting for block-producers. Having a totally liquid token opens up some avenues for malicious witness voting (especially when the market cap is low).
This is especially true with steem since staking also gives you the ability to distribute the inflation.
What would be the benefit of your proposal? Can you quantify it or measure it's effects? Is their empirical data that sugests that it would have a positive influence on the price or token distribution?
It is not a proposal. It is brainstorming idea of improving staking (not removing) without locking up token.
He's not proposing a totally liquid token, since you need a month to power up. You cannot add and remove influence instantly.
And removing the SBD and changing steempower to staking clearly reduces the cognitive load.
