The only problem with your logic, is that Steem and Steem Backed Dollars will eventually lose all their value, because all the people as you say making returns on their investment are bot accounts, and do absolutely nothing positive for the blockchain.

What value could a currency have if it serves no purpose I ask you?

The top earners on here post the same lame shit everyday, and the same idiots all up-vote them, but nobody real is actually engaging. Then come the third worlders, leaving the same copy and pasted comments on said posts... again no value... so I ask again.

What value will Steem or its dollar have a year from now, when the whole blockchain is auto-bots spewing shit content to the top each and everyday?
