With all due respect...
These are at best poor answers. Let us examine them.
You wrote: " Geneology is traced throught the father, but you can still be of a given house through the mother (as illustrated by the fact that the Jews currently trace lineage through the mother due to the holocaust making lineage very difficult to trace, especially throug fathers)"
It is a yes or no question, if genealogoy is traced through the father then the mother is out. The OT clearly states that genealogy is based solely on the father.The point about Jews tracing lineage through the mother is incorrect. For someone to be Jewish their mother needs to be Jewish. However, their lineage is through the father only. This is not recent due to the Holocaust, this is the way Judaism has always been (this is recorded in the Talmud). Why this split is a different question it is based on the oral law, however it has no bearing on the discussion here because Christianity denies the oral law and goes soley with the OT (if you really want to know look in the talmud at the end of kiddushin). The fact is, from the OT alone, all you see if that lineage is paternal.
You wrote: "Also, by being the adpoted son of Joseph, he gets the legal rights as well. He avoids the curse of Jeconiah by not beeing of his seed, but still gets the legal lineage to David through Jeseph and the blood relation to David through Mary"
Unfortunately, if you think about it, this makes absolutely no sense. Even ignoring the obvious problem that lineage is only paternal, neither genealogy is fit for the Messiah (Joseph's because of the curse and Mary's because it is not from Solomon) Therefore 0 + 0 = 0. How does it help that Mary's line avoids the curse, Mary's line still can't be the Messiah because it is not descended from Solomon. What you propose to do, take the 1 point that you want from Joseph, namely descended from Solomon and throw away the rest, and take the 1 point from Mary that Nathan was not cursed and throw away the rest is laughable, the bottom line is that Joseph was descended from Jeconiah who was cursed and Mary was not descended from Solomon making neither of them nor their descendents fit to be the Messiah.
I am absolutely amazed. This is not a side issue, this relates to the basis of Christianity, yet, no one can give a clear and reasonable answer how it is even possible for Jesus to be the Messiah based on the lineage given in the NT.
