ron paul makes a good point why bitcoin would not be a good replacement for the failing 'in god we trust' to print and manipulate dollar, he says: "On reason Greece has been forced to seek bailouts from its EU partners is that Greece ceded control over its currency when it joined the European Union."
http://ronpaulinstitute.org/archives/featured-articles/2015/july/12/greece-today-america-tomorrow/bitcoin would be just like the euro.. it would not work. only a metals backed currency will work as a replacement for the broken dollar 'interest to infinity' debt slavery system.
The loss of control you are talking about occurs as much with metals as it does with Bitcoin.
And of course Texas is asking for gold, not Bitcoin from the fed because the fed is (supposedly) holding gold for Texas and not Bitcoin. (Though the point you were trying to make (Texas would prefer gold over Bitcoin) is likely also true, it is not directly relevant).
