You're playing semantic equivocation games to insinuate that the "trait" of having land is understood to be the same as some kind of genetic trait. These are not the same even if the language we use to discuss them lacks the granularity to clearly delineate them without going into specific definition setting tangents. When this discussion started, it was by way of Eugenics, a theory of breeding that simply did not exist in the time period of Charles II. The Hapsburgs could not have been trying selective breeding as it was originally brought up in this thread because the underlying ideology and science required to enact it did not exist.
We agree that the Hapsburgs could not have been trying Eugenics-style selective breeding because they lacked the science of genetics.
I maintain that they understood breeding domestic animals very well, and they tried their best, with the resources they had, to selectively breed "better" (aristo) people. (Much of feudalism makes way more sense if you start with the axiom that human society should reflect barnyard large domesticate societies) Even we don't know what would be "good genes" for being a successful warlord, so their approach of looking at past performance and hoping for future results (a noble is someone whose family has exclusively extracted rents for a certain number of generations; a royal is someone whose family has sat upon a throne) seems reasonable to me.
In particular, Charles II (like the Ptolemies and Cleopatras of Egypt: https://en.wikipedia.org/wiki/Ptolemaic_dynasty#Family_tree ) has clearly been line bred. (He is his own cousin — in multiple ways. We might quibble over the distinction between line- and inbreeding, but [a] I was trying to be charitable to the Habsburgs, and [b] I don't think that distinction is relevant to this discussion, so I'm happy to call anyone with too few ancestors "linebred")
If you think people would do better with early-20th century Eugenics than aristocratic societies have done over the last thousands of years, we can have that discussion, but I think it's a different one than I had intended. Along those lines, see https://news.ycombinator.com/item?id=39681181 for the problems I would be likely to bring up.
