You are completely right that this is nothing for a maximum security 
usage, not the scenario one would like to have and not what I have at 
home.
But think of one computer which is used together by several people in a 
working group or a shared flat. As the computer itself is physically 
reachable to several people you have no other chance as to trust these 
people not to mess with the computer. In these cases where there is no 
high security possible, you don't really get more security by using 
different keyrings.
