Of course. That is the principle of inclusion monotony. How should it be else?

Right. There is no infinite line.

You are right. No last line. No everything. What do you conclude? Apply to the authorities: Virgil desires that everything should exist. Therefore mathematics has to drop the principle of inclusion monotony?

Alas, in matheology your wish has already been granted, and in mathematics, there are no authorities who could grant your wish.
