The curious thing is, Senator, on that point there is agreement on the left as well. It is just on the left you will more likely hear the issue being government infringing upon liberty rather than infringing upon property. To me, this is the single point separating the two poles as well as unifying them.
What you define as curious, I see as a failure in the present-day Libertarian Party, in which many claim there is no room for persons who arrived from the left-side of the Political BiPolarity. These are also often the equivocators who complain the the LP need temper its more 'radical' propositions in order to achieve broader appear. The problem being that their idea of what is radical is always of the social side of the coin, never the economic.
This is how Bob Barr and Ron Paul get away with being defined as libertarian even though they both believe the government has the right to restrict persons of the same sex to enter into voluntary contracts of domestic partnership. It is how Paul gets away with proposing a constitutional amendment that would define a fetus at conception as a human, but the way he can subsequently claim to be a 'small government' proponent after that with a straight face is a very good place to show he is not being honest when he speaks; he is just another long-term politicians.
This should not be viewed from a pro and anti abortion perspective; it should be viewed from what would be new necessary and proper functions of the government. What should be noted is that if a fetus is a human at conception, then any conceived within the US are also citizens. This would be the largest single entitlement of US Citizenry ever enacted by one piece of legislation.
Another concern is that along with EVERY miscarriage, would come a state duty to investigate it as a potential homicide, and there would be vast new uncharted acts of criminality which any pregnant woman could step into unknowingly. Intent would not be a necessary element of a crime either, as it would still be well within manslaughter laws to be charged even without intent.
It could be possible to prove that a regular exercise routine increased the probability of a miscarriage, other possibilities include, a regular work schedule, becoming argumentative for any reason, taking elective trips which exposed a women to higher risks of accident while being pregnant. The list continues on almost infinitely, and this is not an exaggeration. If a fetus is a US citizen at conception, then the state actors must investigate any "deaths" which happened during gestation for possible unnatural causes, or they would be derelict in the performance of their duties. It called equal application of the law and the reach of the government would have been enacted into a extremely long and intrusive extension.
How many more government enforcement agents would be required? How many new prosecutors, judges and jails?
This is a right-siding and pollution of libertarian ideals, and it is why the left is no longer interested in becoming libertarians. There was a time when I could effectively argue with left-siders that personal liberty had to be both economic and social; that to claim a right to one, was to imply what lay on the flip side came along with it, but far too many persons swollen up with their own Per.Versions of a rightful society must be, believe they possess a divine right to coerce their world view upon others, and to directly impair their liberty.
Maybe the prescription to balance it out again is to start citing Paine as a fount of original intent. There are certainly sections of his work which if embraced would help to deflect the charge that libertarians are just greed heads:
Mankind being originally equals in the order of creation, the equality could only be destroyed by some subsequent circumstance; the distinctions of rich, and poor, may in a great measure be accounted for, and that without having recourse to the harsh ill sounding names of oppression and avarice. Oppression is often the Consequence, but seldom or never the Means of riches; and though avarice will preserve a man from being necessitously poor, it generally makes him too timorous to be wealthy.
