In the mid 1970s we were working on a message switching system for QANTAS.
Someone sat down and did the calculation. The threshold for 'put it on 1/2" mag tape and call a courier' to get data from Sydney to Melbourne (500-odd miles) was a shade over 2 megabytes.
QANTAS were paying $250k a year for a leased line Sydney to San Francisco. 9600bps.
Recalling that makes me feel really old.

In the late '70s I worked for the Rail Technical Centre in Derby. HQ (London) used to send mag.tapes up by train. All was well until they started doing some experiments with 25Kv overhead electrification (not actually powering much, just different designs of catenary wiring). Then the tapes were arriving empty, or at best unreadable. Took about two weeks for them to suss out the problem. That was one test of the overhead wires they'd not planned!

That strikes me as an unrealistic goal.
A better goal would be to learn the basics first.
The difficult we do right away...
...the impossible takes slightly longer.

At a mere 200 pages, there's no way a book on this huge topic will do any serious amount of diving into it. Why the page limit?

Sorry, but you won't be able to find such a magic book.
In networking, and specially with network security, it is all hands-on learning, it will take years of experience, with success and lots of failures to learn what you are doing. Should be doing. Or not.

I got simple network code running fairly quickly using the microsoft website documentation for the language I was using. C# at that time. That was even easier than reading a book about it.

I see you're ramping up these thoughts, and jumping to conclusions.

It seems you finally caved this time. But answer me this: can a fossil hunter who works in the sun ever be a pale-ontolgist? Bone-ous points if you're correct!

I understand how he could have built the ramp and lined up the 50 chariots, but how did he convince the horses to jump over them?
