If you multiply every number by 2, then larger even numbers than all
hitherto present even numbers are created because the number of
numbers remains constant but the odd numbers disappear.

No, not if you really multiply *every* number and not only finitely
many.

When their number remains and half disappear, then half are added.
 

The *cardinality* is the same.

Cardinality is irrelevant. x = x/2 + y.
