Why? Just because it is the smallest object we know? Is this a
self-evident commonsense, or a conclusion from physics?

As I said before, this is a very strong version of reductionism. It
was widely accepted in the time of Newton and Laplace, but I don't
think it is still considered as a valid theory in philosophy of
science. This position is not only unjustifiable, but also lead the
research to wrong directions. It is like to suggest an architect to
analyze the structure of a building at atom level, because all
building materials are made by atoms, after all. The fact that all
building materials are indeed made by atoms only makes the suggestion
even more harmful than a suggestion based on false statements.
