Of course it isn't "too big to fail". Even banks aren't. Despite recent history large banks have failed often throughout history. There's no such thing. It may take down the supporting sovereign government (Dutch East Indies) but life goes on and new political orgs appear. People be people.

Too big to fail is a very recent modern myth. Go back 100+ years and lots of banks failed leading into the Great Depression.

Every system has a break point.

Right. You do have a point, and I think Dutch East Indies is a good example, but I feel this is discussing semantics. Too big to fail, I interpret in this situation as the government having a strategic reason to keep it afloat so it will probably prop it up in case something goes wrong. This makes it have a much more stable position.
