  Minimum information quantum gravity (MIQG) is a theory of quantum gravity
which requires no explicit microscopic quantum structure. In this article, it
is shown that the MIQG action can be derived using a more elegant and
straight-forward method than in the first existence proof. The required
assumptions are dramatically reduced. In particular, former assumptions
referring to the existence of quantum boxes, the exact differential of the
entropy variation and the role of the boundary can be omitted. Moreover, the
open problem of the quantum occupation number per box is solved. Thus, the
arguments in favour of MIQG become even more stringent. The remaining
assumptions are 1. the principle of optimisation of the resulting per imposed
degrees of freedom, 2. abstract quantum number conservation, 3. the validity of
the laws of thermodynamics, 4. identification of a macroscopic parameterisation
with space-time and 5. unspecific interactions. Although the requirements are
reduced, all former results remain valid. In particular, all well established
physics as special cases (Quantum Field Theory, QFT, and General Relativity,
GR) follow and all measurable quantities may be computed.
