Did you even read your link? In the case you cite, the one citizen parent failed to establish, via his presence in the United States for a sufficient duration prior to his son’s birth, grounds for the child’s birthright citizenship as statutorily defined by congress.
And, in the Thomas case, his citizenship is not "saved" by pretending, for purposes of law, that US military base abroad is US soil.
As for the child whose citizen parent or parents DO meet the statutory requirements, there is a significant body of SCOTUS case law that refutes your claim that they are natural born citizens. Rogers v. Bellei, Montana v. Kennedy, Wong Kim Ark, Miller v. Albright, to name a few cases.
