Unsustained growth is just one type of growth though and this affects all growth so I don't see you point as relevant here.

That's a natural outcome in any complex system. It's not reasonable to assume that changes can only affect some parts and not others. What's important is not the first-order changes, but the second-order equilibrium that such a change engenders.

What's important is that unconstrained growth is meaningfully checked. This at least makes it possible for others to thrive, even if they're asked to adapt to a new paradigm. I don't see how a thorough analysis could ever ignore this.

I'm commenting on one of your older comments so it doesn't appear in the current discussion.

What I think needs to be adjusted with GR is simple: Just as time dilates, t'=γt, gravity emission itself must time dilate: g'=γg.

In the case of GR, just replace t with g. t'=t√(1−(2GM/rc^2)).

The problem here is solving for gravity self-interaction concerning gravity emission.
