I agree with this 100%. There's no reason to want SBD as there is no use for it. Pricing tokens on Steem Engine in Steem is bizarre, as it can fluctuate thousands of percent. So it's hard not to see your Steem entry price for a steem engine token as a massive hit if you believe that Steem can be back up at the $8 mark again. I reluctantly purchased a steem engine token, but had the opportunity to sell it to someone who had a better use for it. While I received enough to buy another token to continue my project, I prefer to hold on to that Steem on the hope that one day it will be back at a $1 or even $10.
The whole idea of a stable dollar peg is to avoid situations like this. There's no confidence in sinking Steem into things if the value could fluctuate either way by thousands of percent. Steem Engine tokens and Spinterlands etc should be using SBD as the currency of exchange.
