Aside: Of course this nonsense shows already that set theory is such.

A limit is the continuation of the finite into the infinite. But that

is not used in my proof.

You are not well informed. Read my proof again (and again, if

necessary, until you will have understood, if possible): In analysis

you calculate the limit. This limit contains numbers or (in the

reduced case of my proof) bits 0 and 1. The number of theses bits is

the cardinality of the limit.

In set theory it is similar. The number of bits in the limit set is

the cardinality of the limit set. And that is oo in analysis and it is

empty in set theory.
