Now your starting to get the idea.  As stated in the prospectus any product, commodity or index can be used as the basis of value of the tokens to determine and hold the value to in the units in the crypto block chain.  From the start or over time “The Trust” may change what they decide to use as as a base value index or the name or any settings in the infrastructure.  In this model all decisions are bases on votes of the holders of coins in the chain much like decisions are made in corporations.     BeerTokens with Beer was only chosen in this example as  a means to communicate the concept of a method and the infrastructures needed to support such a concept and a proof of concept.  The names used and indexes or commodity used have no real bearing on the concept method of creating a stable crypto currency.  It's only to illustrate  the infrastructure and tools needed to support such a concept and proof of concept.  To make it simple anything can be changed it's all up to you “The Trust” holders.  And I and others continue to build the other parts of the infrastructure to make this and or other possibilities a reality.  So step up and be counted to make your mark to help shape the future of mankind.  Don't continue to be a helpless fish in a barrel, at the whims and under the control of the software developers, miners and or politicians and bankers.
