Predictions: at best some incoherent rant that they can but won't do it for some bullshit reason

My whole point is I have no desire to give weight to an anonymous someone's bare statement that has no supporting data and consider it to be a law.
Ah, so the gas is exerting pressure trying to expand the confines! Precisely.
So, we're back to a model where, logically, the pressure should be equal throughout the balloon, as the gas is working to expand outward
Not relevant here, actually! These are rotational forces. We're talking about air in a container.
But it's not sitting. It's expanding
How about many hundreds (likely thousands) of non-anonymous statements and all the supporting data in the world coupled with none which contradicts it? That's the case here.
You can continue to refuse to research/read and doubt the former all you like, but the latter is undeniable. You cannot measure or find anyone who has measured anything to contradict the law. That's what makes it a law (and no other reason; publishing, anonymity of author, etc do not factor in in any way)
If gas itself had no weight, indeed that might be the case. Because the gas has weight, and that weight exceeds the expansion force of the gas - it isn't. In imagination all things are possible - not reality.
It's an analogy... It is conceptualizing/modeling the same phenomenon from 2 different angles/directions. In this regard, what we are talking about is virtually identical. You can conceive of the gas applying the force (of pressure) outwards or the walls applying it inwards and either (or a combination of both) will work fine. As long as you are consistent, it doesn't matter - your equations will work and apply to what we observe.
The reason the law is that the gas pressure is derived from the container walls is because there are no measurements of gas pressure without such a container and there are only measurements of pressure inside a container. Indeed, the entire concept of "pressure" is nonsensical without such a container. Gas expansion (indeed, any motion) without a container, at best, would/could be called wind.
Until it cannot anymore! It is prevented from expanding more by the confines of the container and the weight of the gas itself. Gas reaches rest too - or if you prefer, equilibrium.
It continues to try to expand, as that is gas' nature.
