By US do you mean human beings or human ideas or human efforts or all three of any two of these alternatives?<quoted text>
" the government is us"
See, human beings contribute to forming a government/nation by first intellectually defining these terms and then giving these intellectual ideas a concrete shape by creating laws and erecting infrastructure and marking out geo-political boundaries and creating an army of personnel to help in the smooth functioning.
What I mean is this - without a mental conception of the terms government and nation they wouldn't come into existence. For example, a national geopolitical boundary does not come into existence on its own despite the physical parameters like land and landforms being present as an objective reality. To create a geopolitical boundary, human intelligence is needed to first give a precise meaning to what a geopolitical boundary means or what it means to cut off a certain landmass from the neighboring landmasses in order to create a geopolitical boundary in this way. After the initial perceptual/reasoning phases are done with, it's time for concrete action and so the required landmass is marked off by human effort and this geopolitical border or boundary that is created then becomes a reality.
Also note that all throughout the making of such a boundary based on earlier intellectual conceptions, the intellectual faculties again play a critical role in the marking off process where last minute changes may be made.
After the geopolitical boundary takes concrete shape then, too, human perceptual and intellectual faculties and human effort are needed to maintain it and protect it from damage, invasions etc.
So, ultimately, we see that if there's no mind, there would not come into existence a geopolitical boundary since inert matter cannot assume all by itself a well-defined geopolitical boundary the precise way human intelligence would actually conceive and implement it.
The same analogy applies to laws, infrastructure, technology and every input that goes into forming government and nation.
Bottom line - we first conceive, then execute.
Every aspect of human effort, and perhaps of nature too, is based on this basic principle of conceptualization followed by execution.
Of course, the process of conceptualization followed by implementation of the thing conceptualized where humans and nature are concerned are based on different scales but nevertheless the same thumb rule is used.
Besides, once the basic intellectual blueprint is executed in a concrete manner, then, too, intelligence is needed to keep watch over the created form/created institution and to make intelligent changes based on intelligent observation of what more could be done.
So, mind is primary.
