I also don’t like the use of the word, infinity, used to describe something real.  While there may be infinities or infinitesimals in theory, I do not think anything real can be as such in practise.

his point is very very small.

actually "vision" degrades with smallness, microscope is about 1000x
magnification, electron microscope 1,000,000, then special ways like
mapping charge,  then thermal noise dominates as atoms move around.
a long way from infinity small, in fact an infinity
