O, and what I forgot to highlight is that such a coin will to a very high degree be free from market influences on it's value and will effectively be a link to reality for that economy. There will exist only a fixed number of tokens per capita circulating in this trading environment. None of these trading tokens will ever leave the system. Taxes cannot be levied, at least not in a monetary form, and should an account holder run out of tokens, that account holder will be incentivized to be productive and sell something in order to regain purchasing power.
