As a statement of a discrete binary status, that is simply not true. 
Some people may believe or desire it to be true, but that does not make 
it a useful premise when devising new mechanisms for use in the real 
world. the real world.

Beyond the proximal counter-example which is most obvious to myself, 
note instead the widespread (at least in the US) use of addresses in 
consumer freemail (e.g. yahoo.com, hotmail.com,gmail.com) and consumer 
ISP domains as business addresses by many small businesses. On the other 
side of that fuzzy grey band, it is not uncommon for small 
privately-owned businesses which have their a "business" email domain to 
have a few addresses established simply for the convenience and/or 
vanity of family and/or friends of company principals.

One useful (although never officially stated) research finding of the 
IRTF ASRG when it still existed was a solid demonstration via SPF that 
conceiving an anti-spam scheme with behavioral premises that aren't 
quite true does not inevitably result in the fully developed and 
deployed anti-spam scheme driving the inconsistent behaviors into 
extinction. With SPF, the result has been relegation to weak uses and 
narrow applications where it never threatens those behaviors.
