Yes but
that description doesn't make us
any better off than we were before.

"Finite is finite." So?
Our over-arching strategy is to _start_ with
claims true of each one of whatever we're
reasoning about, and then _keep_ that
being-true-of-each as we advance to further
claims.
The more true-of-each detail we start with,
the more we have to work with, when we try to
find claims we care about to which we can
advance in true-of-each-keeping ways.

Your undefinable finites are not in FISONs.
We can start with being in a FISON as
a description of one of what we're reasoning
about, and then none of the claims we start with
or advance to are about undefinable finites.

Because you decided to call "finite steps"
things which I am NOT talking about.
However,
I am STILL NOT talking about your other things.
An ordered collection
which begins at 0 and ends somewhere and
which, for each split, there is a
predecessor-successor pair across it
is
an ordered collection
which begins at 0 and ends somewhere and
which, for each split, there is a
predecessor-successor pair across it,
no matter what you or I or Georg Cantor
call it.
We reason _from the description_
You call something else a blablablah
finite step, but you haven't changed
_the description_ from which I'm
reasoning.
