Yes, this is exactly the point by the prize. The question is to show
how something like this could happen spontaneously.

It requires violating local thermodynamic equilibrium. I'm working on
an article and a few presentations for upcoming conferences where I
explain this in detail. This then proves that none of the current
models for prebiotic chemistry can explain the origin of life.
There are not models that assume thermodynamic equilibrium. Biologists
aren't stupid. They all know that abiogenesis requires a source of
energy as low entropy. Urey showed that lightning can create organic
molecules. Nick Lane has a theory based on alkaline vents on the ocean
floor. He bases this on the ubiquity of ADP->ATP as the energy carrier
for all living organisms. These vents form complex mineral structures
which provide the kind of micro-environments you mention.

A viable scenario is to get to a large random organic structure forged
in an interstellar ice grain, where organic molecules at low
temperatures under UV irradiation will only interact with nearest
neighbors. Thermodynamic equilibrium is never reached, the system
moves farther and farther away from this as the reactions under UV
radiation continue. This way one gets to large so-called percolation
clusters of organic molecules that have a random structure.
Such random organic structures look totally useless to explain the
origin of life, because what you want are the very specific molecules
that are involved in the biochemical processes in living organisms.
However, the structure of these random organic molecules is such that
it has interior structures with compartments containing large random
polymers and random interior surface structures. These can then serve
as micro-environments within which prebiotic chemistry under normal
local thermodynamic equilibrium conditions can work. With a finite
number of N structures in a compartment one will break symmetries such
as chiral symmetry at a level of 1/sqrt(N). Small molecules can escape
the compartments via pores in the random structure while large
molecules get trapped inside.

"What You Must Do to Win The Prize
You must arrange for a digital communication system to emerge or
self-evolve without "cheating." The diagram below describes the
system.
Without explicitly designing the system, your experiment must generate
an encoder that sends digital code to a decoder. Your system needs to
transmit at least five bits of information. (In other words it has
to be
able to represent 32 states. The genetic code supports 64.) "
