3/10 of 1% of the vote in the last presidential election suggests considerable dissatisfaction with Libertarianism.
As to "dogmas fall[ing] apart", you have yet to demonstrate any point at which the "dogma" of individual liberty and personal responsibility fails in real world application.
As previously pointed out, an absolute right of contract would allow for indentured servitude and other forms of slavery forbidden by our 13th Amendment
Illogical. A libertarian regime is not the current state of affairs. It has also not been widely recognized as a desirable new state of affairs. Hence, little motivation among voters to act for change in that direction.
When the proposition was first presented that the earth is round, and not the center of the universe, it was met with vehement scorn, and its proponents were widely regarded as heretics. But they were right!
As previously pointed out . . .
And rebutted. A rebuttal to which you have not responded in any substantive manner. Here's more:
The term "indenture" refers to "A contract binding one party into the service of another for a specified term." This dictionary definition makes no reference to such a contract being involuntary. The XIII Amendment specifically prohibits involuntary servitude, and the two terms, indentured and involuntary are not synonymous. To elaborate, when one enlists into military service, one is entering into a state of indentured servitude according to the definition above. Surely you would not insist that, in the absense of a draft, this is involuntary servitude or slavery?
