Our founders were far more prescient than Rand. They understood that limited government would require a disciplined population willing to morally constrain their own behavior and excesses. In the absence of such, people start pressing government for more laws and increasingly intrusive regulations. When people abandon personal morality, they allow government to become the arbiter of public morality, hence smoking a cigarette is now one of the most unholy acts a person can commit, but wrenching an unborn child from the womb in pieces is not merely a protected right, but virtually a blessed sacrament. Why? Because government says so!
Also, unlike Rand, who despised the traditional views of "altruism" and, "self-sacrifice", our founders understood that people would sometimes have to commit to, and sometimes sacrifice for things greater than themselves, hence their willingness to pledge their lives, fortunes and sacred honor for their countrymen and for future generations.
The expression of your reasoned mind is as brilliant as a bell pealing high and clear through a hushed and frozen winter’s morning.
