Then d is the union of all its FISs. But in proper set theories, the union of a family of sets need not be one of the family, and unless the family contains a maximal member, which the family of lines does not, cannot not be member of that union.
So WM is claiming the existence of a maximal set in a family of sets carefully constructed so as not to have any such maximal member.

NO, it is the union of the list, but as the list has no maxmal member, that union cannot be either the list or a member of the list.

If everything in the list is in one line of the list, and each line is a FIS of the next line, then everything must be in a last line, and the list must be actually finite.

Outside of WMytheology a number cannot be accepted as a natural unless and until it is known to have a successor.
The existence of a successor is a requirement for membership in the set of naturals.
So numbers not already known to have successors cannot be known to be naturals at all. --
