b. Complex life requires a pool of these self-catalyzing devices to be present in the same place and time such that they can compete with one another. A cloud of gas or small specs of nanometer scale dust expanding forever into the void cannot become complex life.

c. Complex life requires the environment to be stable enough that the information - the catalyzing "something" - is not destroyed faster than it can be created. This also means there must be an energy gradient to create information. Thus, a ball of matter at a smidgen over zero kelvin can't create life, no energy gradient. The hot gas cloud of our sun doesn't support life starting there, too much disruption for it to ever evolve.

And like 10 others, point is, gravity waves fail the first test and many other tests will fail out a great many other possibilities.

*Ok, I apologize for being harsh, but I don't see how you could have "envisioned" this working. You would have needed to think of a way for a gravity wave - which requires mass to be created - to catalyze the creation of an identical gravity wave to itself, or a sub-component of itself that can be assembled into itself. That's the first step towards life. The very first one.
I have to admit it would be difficult to imagine how gravitational waves could form the necessary structures that we might recognize as being something akin to light, but they are non-linear (i.e. gravitational waves interact with gravitational waves unlike em waves)
