If this universe contains agents who engage in acausal trade, does that make it partially acausal?
Nope. It's just a terrible name.
I almost went with that answer, and didn't ask. But then I thought about trade with future agents who have different resources and values than we do--resources and values which will be heavily influenced by what we do today. The structure seems to be at least as similar as self-consistent solutions in plasma physics.
By 'acausal trade', do you mean:
or
The first is causal (but does not preclude the possibility of the universe containing other acausal effects), the second is acausal.
Agents can make choices that enforce global logical constraints, using computational devices that run on local causality.
Thanks, I feel like I grok this answer: There may be higher order acausal structures in the universe, but they run on a causal substrate.
Nope.
