Correct. That is because the asserted aim cannot be established. In

order to reach a goal that is impossible to reach, no attempt is

necessary.

Why only finite sets? What property is changed if infinitely many are

there? If there are infinitely many unnecessary lines, they all can be

removed - by their property of being unnecessary. Otherwise there must

be some necessary line among them.

You try to cheat: If we have infinitely many unnecessary lines, then

some of them become necessary. But of course, we cannot find a first

one of this miraculous set. Do they all remain sets of natural numbers?

Or will also this property transform? And why?

You claim that there is a sufficient set, but every line you have

offer ed up to now is not necessary and not sufficient. Amazing that

you want to sell that as mathematics.

Correct. That is because the sets are only believed to be sufficient,

but in mathematics in fact, they are not sufficient.

Try to answer this question to yourself: Why do you claim that an

infinite set of unnecessary lines must not be removed completely,

i.e., contains lines that must remain, but an infinite set of natural

numbers must contain only natural numbers?
