It is enticing but the only concern here would be that the counterpartbof the transaction would impact Steem and it could have unintended consequences to the supply of Steem on top of what some are already concerned about regarding the inflation. I have heard that witnesses are able to put an interest to SBD balances which could raise demand and peg it to the $1 as well. I do think that SBD is key to the ecosystem given its capabilities for transactions both internally and externally but it does not have the liquidity needed at this point yet.
