What are ubiquitous ordinal?>The "ubiquitous ordinals", sort of recalls Kronecker's
"G-d made the integers, the rest is the work of Man",
I think Kronecker's integers are the finite ordinals.
Are you saying that 'ubiquitous' means 'finite'?

It's surprising how unhelpful some answers can be.

Consider the definition of a finite.cardinal as
the cardinal #A of a set A
smaller.by.one than sets fuller.by.one
#A ∈ ⟦0,ℵ₀⦆ :⇔ (#A < #(A∪{a}) ⇐ A ≠ A∪{a})

If,
as might be expected,
infinity.plus.one is different from simple.infinity,
then,
under that definition,
infinity is finite.
