So national defense is the only thing for which the federal government was intended? Why not break a habit and actually examine the facts? The Declaration of Independence, one of the founding documents that you pretend to understand and revere, puts it explicitly: governments are created to ... provide for the common defense AND promote the general welfare. You libertarians prefer to ignore the latter phrase out of egotism, arrogance, and short sightedness. You convince yourselves that you do not need public assistance and never will, ignoring the example of your hero, Ayn Rand, who eventually applied for the entitlement benefits that she had spent her life derogating.
