Indeed. Problem is, I don't believe in positive security models in the real world (with the theoretical exceptions of some military or SCADA networks that actually don't connect to the PSTN [still waiting to see one]). If we start now we can build a ground-up secure network just in time for it to be completely obsolete and we all retire in frustration..

We can split hairs on this, but if you load your perfect web server code on an operating system, then the integrity of the application evaporates.

Customers tend to favor building networks out of components as opposed to mining the iron ore, shaving crystals of silica into wafers and carving transistors with razor blades.
I tend to favor buying cars with the wave-front topology of the combustion chamber already engineered to my satisfaction.
Practical solutions apply beyond the purists' and hobbiests' worlds

Just Say No to Dittoheading!!
If you want to live in a world in which the computer is a panacea rather than a plague, there are a few crucial things that must be done. Do not leave the responsibility for the social impact of computer applications in the hands of technicians. Insist on individual, government, and corporate responsibility and liability for the computer's effect on people. Recognize the computer as an inanimate tool with enormous potential for either good or evil, the choice of which is in the hands of men and women, not inanimate systems.
Our government is designed so that you are neither dependent on the excellence of your leaders nor vulnerable to their failings; so too should you be free of the men and women who make and run your computers.
