Is there another rebuttal to Rayiner you might have that would be persuasive to someone who is not sympathetic to ancap philosophy?

The idea that rights are the sole domain of individuals and that groups (whether constituted as states or otherwise) have powers, but not rights (powers which are legitimate only so far as they extend from and do not contradict individual rights), is fundamental to classical liberalism, not a belief unique to those “sympathetic to ancap philosophy”.

No, you said "Communities have the legitimate power to do what you describe so long as no individual rights are violated." That is not in fact a principle of classical liberalism, which favors individual rights but is not controlled by them. American conservatism draws from classical liberalism, for instance.

You missed a “not”, and yes it is a core principle of classical liberalism; indeed, classical liberals tended to see powers of government as legitimate exactly to the extent they served individual rights, as they perceived those rights. Locke, for instance saw the realization of the rights to life, liberty, and estate (which he collectively labeled as “property”, thought that term often is used equivalently to how Locke used the “estate”) as both the motivation for entering into government by the people and the function whose service defined the legitimate role of government.

Both Americans conservatism and American liberalism draw from classical liberalism, without being entirely within it, but I'm not sure what your point is in raising that about American conservatives, since explicitly echoing Locke’s position on the legitimate role of government (with perhaps a narrower understanding of property and thus individual rights than Locke stated) is a central refrain of American conservatives, especially those most likely to explicitly cite continuity with classical liberalism.
