Then the invention was futile for your purpose was not achieved, as at
least infinitely many of those lines are necessary and have been proved

Theorem: Every finite union of lines omits some naturals and every
infinite union of lines includes all naturals.

Wrong! That implies a condition contrary to fact.
But one can show that every line that is not A last line is not needed.

Since the union of all infinitely many lines/FISONs together is clearly
sufficient to contain all naturals, there may be some minimal condition
on a union of lines which is a necessary condition, and that minimal
condition is that the set of lines/FISONs to be unioned is infinite.
And WM has still not validated his claim for existence of a linear
mapping from the of all infinite binary sequences onlt the set of all
paths of Complete Infinite Binary Tree. A bjection is trivial, a truly
linear mapping is well beyond WM's skills.
