I am staggered by your complete lack of understanding regarding our form of government and the thrust of the two trends of political thought today - socialism and free enterprise.
You have everything turned on its head. You are truly enmired in a socialist mindset, yet somehow you have got this confused with conservatism, individual liberty, and limited government. It's staggering that all these confused idea could co-exist in the same mind. It must be wonderful to be you.
Just one point. NO government, not our government, not ANY government, from the beginning of time, was ever established to protect individual liberty. That idea is rubbish, complete and utter trash. It is an idea unworthy of the human mind. I can't imagine where you ever got such a totally bizarre notion.
Governments are established to secure peace and security, and economic stability. Individual liberty is always, of necessity, placed at risk by the establishment of government. That's why perfect individual liberty is epitomized by the LACK of government, not by its establishment.
Ever hear of anarchy?
Our government is particularly characterized by limits placed upon it by the founders to protect individual liberty (enumerated powers, for example) from the powers of government. But this is surely qualitiatively different from the reasons for its founding. The two are different, most profoundly so.
You are confusing the reasons for the establishment of our government and the structure and constraints upon it established in the mechanisms of its establishment.
Your errors of thought just go on compounding from there, without restraint or constraint, leading you to horrible errors of logic, leading you to insupportable conclusions, and to the deluded beleif that you are espousing conservative values when nothing could be further from the truth.
