I know it's all been said already in other comments, but just to get my 2 cents (or about 0.0026585 Steem, lol) in.
I honestly don't see the complexity being an issue for non-crypto people. In my opinion they are going to have to go through a near identical ramp up process to understand Steemit with or without the SBD. I still see us having the same non-crypto adoption issues regardless.
I do want to note hear that with the big benefit of the SBD being a way to 'not worry' about the inflation issue (which is not so much an issue after the economic changes) and volatility (which we're still somewhat dealing with due to the quick powerdowns/selloffs.)
Personally I'd at least like to give some time before doing away with the SBD, like 3 months since were about 2-3 weeks since the new power down schedule kicked in. This would allow the volatility from the 13 weeks of sell offs to ideally end and things can ideally stabilize.
Right now with steem being about 13.3 cents, we are nearing the scary points of the Steem Marketcap to SBD debt ratio that we had seen before...right now about 24.43%. While we do have some measures in place to deal with this (such as being paid out in all steem anyway) the fear of the SBD debt looms yet again, which makes the black swan concerns always come back. When steem prices go down, each Steem Dollar earned/bought at a higher rate require more Steem to pay off the debt/contract. (1 SBD while Steem is at 25 cents would be a call for 4 steem, when the price is at 10 cents, it's 10 steem.)
These concerns are something that I do fear when this debt to marketcap ratio gets high like this because nobody wants to see the price crash, potentially killing the currency and Steemit as a whole. (At least that's my understanding, I could easily be mistaken here.)
Long story short (...too late,) I don't see us doing away with the SBD in a few months, with simplicity being a rather moot point and the relief on the economy itself being a plus.
I do see the my own benefits, and ease, by being able to hold a SBD to protect myself from volatility. However my desire to have the Steem economy to survive as a whole outweighs my individual benefit/ease in this case, in my opinion.
No idea where you got that number. It is actually about 3.5%.
I just took market cap divided by sbd balance online. Easily could've been a case of late night math. That can happen. Sry.
