Thank you @littlejoeward, for bringing up all these points to iron out.

I am of course never really replying to you personally only. Your questions create the opportunity every time to embroider on ideas that other readers may find thought provoking. I do not see this as a project or agenda of my own that I wish to foist on the community. I see some basic concepts with the potential of us all together getting something sensible going.

Coming back to your question..
I think we are seeing two different scenarios here. The SBD is exposed to speculation on a 'foreign' market here. Steemland treats the SBD internally with care. On the world wide exchanges all kinds of strangers, people that are not stakeholders in steemit, can throw money at, it chasing up the price.

One could have it that in 'Energyland', only accountholders/players in the game will be able to trade amongst one another with the tokens, so all will be subject to the same forces.

And to make it possible for the game to last forever, one can put a limit to the total number of tokens that can be held in an account - say a few million. That will have players store additional value in real assets - property, useful things, luxuries, gold, whatever, while preventing inflation.

The individual accounts will then not be the ultimate sores of value..only to a limited degree. The accounts will primarily be a means by which to fairly and evenly and sensibly inject purchasing power into the economy at a grass roots level, instead of as at present into the top echelons of society, from where it does not "trickle down", hence the poverty at the lower end.

There will never be only one currency either. Virtually any commodity can at any time serve as a means of exchange. And other cryptos can be around as well - why not?
