Pretty much any information can be used for something. You're ignoring everything they say about how something not critical to application security may still not be desirable to be leaked for other reasons. Example: Target and Walmart may not depend on satellites being unable to image their parking lots from the perspective of loss prevention or corporate security. But it still leaks information they may not want financial analysts to know about their performance.

You've used an analogy instead of an example to demonstrate your point: analogies can be helpful for explaining concepts but are rarely accurate enough to prove logical parity.

It would be much easier to discuss the merits of your argument if you had an example of the dangers of leaking creation timestamps for database entries.

Otherwise, carparks & database creation timestamps have nothing in common that is meaningfully relevant to your argument. You cannot just generalise all worldly concepts & call it a day.

Sam Walton used to fly investors in his plane over Walmart stores and ask them to count the cars in the parking lot, then he would fly them over competitors stores and ask the same. Just a fun fact about how this is a very real scenario!
