Because that is ultimately the reason why SQL behaves the way it does.  I'm 
sure we could all come up with a long list of behaviors that would 
be "useful" or "better" or "intuitive", and we could also come up with a long 
list of reasons why such a database system would be totally crappy.  You only 
need to check with our friends in Uppsala for some examples.
