This is an economic or ergonomic theory of the universe? It seems
anti-anthropomrphic - i.e. if it were 1 then theorists wouldn't be
needed.

I recall the bounded states argument, but not very well. Something
about the quantum size limits as related to the very early universe and
the information equivalence between the event horizon of a singularity
and what has gone into it. The result was something like - # internal
states are proportional to the surface area of the singularity horizon.
We can see out to a radius of 13.7 billion light years, so calculate how
many internal states there are in our sphere of influence.

As to energy, it seems strange to me that energy content could grow as
the universe expands, but I grant you that there appears to be some kind
of negative energy pressure pushing it apart, so having less of that
would be more energy for us :-).

Please don't boggle my mind about what this means for conservation of
energy - what meaning does that law have if negative energy exists?

And where did that initial energy come from? Somebody is going to tell
me that it sums with the negative energy to be zero, so we could
calculate the repulsive force exerted by negative energy from
observations of positive energy (and mass) and the observed expansion.

And then what about those weird p-brane arguments about the universe
being a collision between branes, and the weakness of gravity being due
to gravity having gone off in the other brane ...

We don't need to go so far. Just let the OP import an nfs export from
somebody else (who has imported an nfs export from somebody else ...).
