The solution is that it is a matter of temperature. That a lumpy

gravity is involved is only true for low temperatures. For high
temperatures, the smooth distribution still has the higher entropy.
That's why the universe has to be cold enough before galaxies and stars
can form.

In as much as galaxy and star planetary system size distributions
are different, are two different formation temperatures required
within the concept of Jeans' length?
