The map and the U.S. geography text are equivalent to "educated people saying it is the case".
Well, no, it's not. We don't believe the maps and texts because someone else does (including the authors). We believe it because we assume those authors gathered evidence supporting their claims --- conducted surveys, made measurements, etc. That is a rebuttable presumption, but warrants acceptance until some reason appears for doubting it (and quite often it does). Public opinion, however, on almost any subject, does not warrant that assumption, because most of "the public" are ignorant on most subjects and will have no evidence for their beliefs. But it doesn't matter how educated the person is. If he can't produce evidence supporting his belief, that belief is worth no more than that of an ignoramus.
The entire peer-review system for scientific journals is a form of ad populum decision making.
Well, you clearly have no idea of what "peer review" entails. It means that others familiar with the topic in question have reviewed the evidence and arguments provided by the author and decided either that 1) the evidence is clear and sufficient and the arguments sound, or 2) that they are not. In the latter case the author may be asked to provide more evidence or repair errors in his statistical analysis. Then, when the article is published, others can try to duplicate the results (and often enough, fail to do so). Peer review is not poll-taking.
Barry Bonds hit the most home runs in the history of Major League baseball. The experts all say he did, and I believe them.
Do you believe them because they are "experts" and said so, or because you assume they actually counted them and could produce evidence for every one of those home runs?
"Life and liberty are "possessions"", and therefore the right to life and liberty are akin to property rights.
I don't think "possessions" is an accurate description of life or liberty. It's an equivocation.
That is not a postulate supporting the conclusion you reject. It is just an observation, and hardly controversial. You don't possess your life, liberty?
"Possess (transitive verb):
"1a: to have and hold as property : OWN
b: to have as an attribute, knowledge, or skill
https://www.merriam-webster.com/dictionary/possess
We don't "hold life or liberty as a property". That's your mistake. We don't "own" liberty; we sometimes have it, and we sometimes don't have it. Life and liberty are states of being, not "possessions". You are twisting the definitions to imply otherwise.
Egads. You assert, "I don't think "possessions" is an accurate description of life or liberty. " I give a dictionary definition clearly asserting otherwise. Now I've "twisted" that definition? Are life and liberty not attributes of (living) persons?
You seem to be construing "possessions" narrowly, embracing only tangible, physical objects. The term has a much broader scope.
Please enumerate those basic principles from which you think you can reason your way to Libertatianism.
You now want a complete argument for libertarianism? How about one for the conclusion you rejected, which was, I believe, "No person has any
a priori duty to meet any other person's needs, medical or otherwise."
Note, first, that that is a
denial of an alleged duty. The burden of proof would fall on the person who asserts there
is such a duty. I asked you before, "What rational moral principle permits Alfie to force Bruno to support Alfie's favorite charity, or any charity?"
You offered no answer (other than the fallacious
ad populum argument).
But the argument for my claim is simple enough: Alfie has no
a priori duty to pay for Brunos' health care because
there are no a priori duties. All moral duties arise from some act of the agent. Alfie may have a duty to pay for Brunos' health care if he has injured Bruno, or made some sort of promise to him, or entered into a contract with him imposing that duty upon him. Duties claimed to exist
a priori are arbitrary and baseless, and usually defended on emotional, religious, or other non-rational grounds.
So I ask again: do you have a
rational argument for that duty?
