No size is required and no size is possible
if this is forbidden.

 Ignoring cardinality changes nothing
about f(k) = k∪{k} and ⟦0,w⦆ and ⟦1,w⦆

Ignoring that Cantor's claim requires to empty the endsegments from all natural numbers in order to use them as indices in mappings (ℕ to the set of endsegments, ℕ to ℚ, ℕ to the lines of the Cantor list for "proving" the uncountability of ℝ) shows inconsistency.
Remark: The mapping from ℕ to the set of endsegments is one of the few true bijections.
