While I agree with you on most points, security is never the number one priority. If it were we'd all destroy our computers, never write anything down, and simply accept the collapse of society. Security is always weighed against many other priorities such as authorised users being able to access data, and ease of use. A unique 128 character password for each document would have high security, but be widely considered unacceptable even in a system handling classified material.
