I admit that your proposal confused me at first, but after reading through the entire post "I get it". More importantly I like it and think it could have a valuable impact on how SteemIt is perceived by the mass internet audience. And this should be the end goal of the SteemIt beta, to tune the system to be the best possible for the widest adoption possible.
I do like your idea about purchasing additional tokens by burning SBD's.
Steem on,
Mike
