If anything external is not tracking what the abacus does, then
nobody counts nothing.

No, of course. Until something or someone who can read the bead arrangment
comes along, and reads the number. The counting process is an abstract
measurement upon a particular physical system configuration. In order
to do that, you need a) an appropriate physical system b) appropriate
configuration c) an agent capable of that measurement. Of course, in
some cases you can have all three in the same entity.

As I already said, some animals, humans and human-derived systems
can do numerics. The calculator keeps track of button presses, so it is tracking
events on own power. The cat couldn't care less, being reduced to the
role of an event generator.
If you instantly rapture(TM) all counting animals, people, and human-derived
systems numbers instantly become meaningless arrangements. Until somebody
or something comes along, and reinvents the concept. Then numbers are here again.
