Re: The members of a set are...?

All I can say is that you have shown that ZFC has changed the meaning of the word set without knowing that it has changed it.

Yes the mathematical word "set" is not the
same as the common word "set".

Similar a mathematical line is an abstract object
that does not exist in reality. There is no
pen in reality that can draw a line as mathematics
defines it.

Because there is no pen only one point wide and
this will yield in a dimension-1 object. The
stroke of a pen will always occupy some area,
and thus be a dimension-2 object.
