As I said the only people who are content with things exactly as they are
now are drug addicts with unlimited supply of heroin.

I don't understand why any society would do that, much less do I understand
why EVERY ET society in the universe would do it? And is Earth the only
place in the  universe that has criminals who don't always obey the law?

That would be a incorrect assumption.

All it would take is the ability to move things with atomic precision and
we know it can be done because we have a existence example, life.
Admittedly it's a crude version of Nanotechnology but it's about as good as
you could hope for considering that it was invented by random mutation and
natural selection. And life was good enough to manufacture me, every atom
that's in me today came from last years potatoes, and life was good enough
to manufacture last years potatoes from nothing but water, carbon dioxide
and nitrogen from the air, and a few trace elements from the soil.  Not bad
but  I have a hunch intelligence can do better, one hell of a lot better. I
should add that the fact that the area human beings are able to
successfully engineer is cut in half ever18 months gives me a hint that
Nanotechnology is making progress. One hell of a lot of progress actually.

It's more like:
Intelligent Life -> Nanotechnology -> Singularity ->Von Neumann probes ->
Dyson spheres -> 50Myrs -> No visible stars

Is you chain of reasoning that ET does exist shorter than my chain the he
does not? I don't think so.

The denominator doesn't grow and nobody is letting it do anything, it
remains fixed, it's the energy produced by the Galaxy. And most of that
energy comes from the minority of stars that are larger than our sun. And
all that energy just radiates uselessly into infinite space. What a waste!
