Then ther is no such thing a potentially infinite, as that would require
existence of a process that does not end.

So for any set of naturals you can name, there is a process for finding
a superset of that set, even in Wolkenmuekenheim.
If one cannot ever have something true for ALL natural numbers, how can
one ever use inductive proofs?

It also means that induction can never conclude that anything is true
for all natural numbers.
In Wolkenmuekenheim one cannot say
"For all n, if n is a natural then n+1 is a natural."
because on cannot ever say "For all n"

Thus WM can never prove that anything by induction.
