You have explained very well about Indebtedness and Ownership in your post. Now it's clear what is debt and what is ownership. Definately Indebtedness and Ownership have great role in ecosystem of Steemit. You have explained very well about Steem network and Centralized Fiat Currency.

SBD printing is stopped when debt ratio is 10 percent or more than 10 percent. It must be less than 10 percent. SBD print ratio is 30 percent here. It's means reward will be given in the form of SBD 30 percent and 70 percent will be in the from Steem and Steem power.
