the arguments I have read for this 'pegging' are to have a stable currency for an economy built on steemit. Let me give you an example. I pay 10 SBD for a months subscription to steemsql. The first month this subscription came in it cost me 70 US$ due to the price of SBD. My monthly gym membership doesnt cost me that much. Now at current prices this will cost me us$ 22. Without a stable price on SBD its difficult to run an business where people know what they will be paying each time for a product or service. For this reason, I understand and accept this reason for pegging SBD.
Now let me change hats. I am an author on steemit and spend many hours preparing an analysis before I do a post. When the price of SBD is higher, I win......simple.
So that leaves me as one of the undecided on what is the best course of action for SBD. My preference, let the markets decide.
Which brings me to my next point. The markets are deciding and as shown with other charts, the price of SBD is following a trend that other coins are following and when it hits $1, well lets see if it does stay there!
As for the whitepaper - I read it some time ago and know at the time it was out of date. For some reason I did think steemit brought out a new one, guess I was dreaming...
