I guess as a Brit, you are not that aware of American history. The American Revolution was fought to free ourselves from the Yoke of the British King (no taxation without representation and all of that stuff). The belief at that time was the smaller, the federal government, the better. We wrote the Articles of Confederation and proceeded to go forward. Immediately things started to fall apart. We formed what was to be known as the Constitutional convention to try and fix the Articles of Confederation. The members of this convention soon figured out that the government under the Articles of Confederation was not fixable, and that we needed to start over. From that came the American Constitution. The whole long debate that occurred was to determine what was the proper balance between not enough central government and too much central government. So there is a balance, and honorable people can disagree over exactly where that balance rests.Remember only one thing.The elders advised utah people to vote for alcohol prohibition - to give government power to prohibit people from drinking/doing stupid thing...sometimes, its good for government to intervene with the right and objective decision, because otherwise our selfish desires (even if they are most noble ) and subjective outlook on things may cause more harm and suffering than good.
However, There is a rather bright line you cross, once you move from simply defining laws of proper civil behavior, and a government taking over the responsibility for the provision of food, shelter and medicine from the individual in exchange for submission to the "benevolent" providers and administrators of those benefits.
