> My point is that not every object with a blackbody spectrum is a neat black box.
Irrelevant. We are talking about an "idealised" black-body. It's the like the joke about physicists modelling a cow, first they assume it's a sphere. You are trying to calculate how temperate correlates to the frequency of light emitted so having a scenario you can calculate is always best. Yes. real objects are not perfect black-bodys so will differ slightly from the idealised case but the difference is typically so small as to be meaningless.

> This seems to me an extremely chaotic environment
The inner workings don't matter since the only think that does is the surface temperature. The Sun, or any star, are actually almost perfect black-bodys since they are nearly uniform, opaque, and non-reflective. There's nothing complicated about the light they emit, it directly comes from the energy they generate.
