I don't know what 'it exists' means exactly, nor what it means to say it is 'printed'. It is a number in the blockchain code. It can't be spent, it can't be converted, it isn't part of any user's account balance, etc. In fact, regardless of votes, it can't even be paid out to SPS proposals at a rate of more than 1% per day.
IMO it shouldn't even be included in 'supply' until placed into circulation, at which point it can be spend, can be converted, etc. but this is of little practical significance right now since the amount is very low (200K out of 7M), as is the rate of increase.
If it's being accounted for by the blockchain as circulating supply, then it is "printed", and it is added as a debt to be paid.
It might be locked and not moving, but it is accounted for, and it does have an influence on the debt ratio value.
And as you said, it definetly shouldn't be included on the supply until it is unlocked.
And 200k/7M is 2.8%, wich isn't insignificant if you consider that the external market debt ratio is around 0.5%-2% over 10%.
So yeah, the way this is accounted for does have a significant impact on the debt ratio.
The 2% (over cap) is a percentage of the total Steem market cap not of the amount of SBD, so these are different numbers. In fact about 20% of SBD needs to go away to get back to the cap and SPS is only 2.8% of SBD.
