That is a non sequitur if there ever was one.  Why should this be the
case?

Think of a mass M as being divided into i smaller submasses (all
with the same mass m_part) and of a mass j of being divided into
m smaller submasses with the same mass m_part. Which submass of M
should not interact all submasses of j?
