Earlier quoted context omitted.
You can't just steal documents from governments and publish them without any consequences. Erm, why ? What's your reasoning here beyond "but the laaaaaaw"? Do you even have any moral reasoning backing that?
So you'd be fine with someone stealing data the government holds on your, say your medical records, and publishing them on the front page would you? Maybe your last few tax returns. May as well publish those as well! How about state secrets on any weak parts of military defences? Yes I have moral reasoning. It's stolen information.
For your first two examples (my medical records and tax records), that is personal information which is limited utility to others. By contrast, the state "secrets" here directly impact the day-to-day lives of thousands if not millions.
Your third example is exactly something that would be beneficial to know--any enemy presumably already knows about it, and keeping it secret from the public at large only serves to allow the people who should be working on it to function without oversight.
As for the actual information being leaked: that is not personal information; a good chunk of it is operations details for state security apparatus, and that's exactly something that I, a citizen, would prefer to know about.
With such great resources at its disposal and so much power at its beck and call, we simply cannot afford to allow the government any secrecy or opacity in its functioning. To do otherwise is to encourage the sorts of corruption and corrosion that turn a state into a horrendous place to live.
