The real world doesn't add raindrops, or most other things we think

constituents are indistinguishable, nature can perform simple
arithmetic with them.
I'd say *we* perform simple arithmetic to describe them - but only
when we correctly recognize what is countable and what isn't. So
the truth of Ax(x=/=x+1) is in Platonia.
Platonia? Where's that, then?
In our heads and in our language (and publications of the AMS).
So, 2+2=4 was meaningless before life appeared on this planet?
I can easily imagine that "2+2=4" was meaningless, but I can't
conceive that 2+2=4 would be meaningless, if only because Platonia is
out of time. It is not related to physics, except that physics is a
persistent illusion coming from the machine's inside points of view in
Platonia.
