  I can give you three:

     1/ LargeISP does not want to spend the X hours it takes to
        bring up a peering session for SmallISP's routes.  The
        benefit gained to SmallISP's 5 routes is not great enough.

     2/ LargeISP does not have confidence in SmallISPs ability to
        properly administer a safe BGP peering connection, and
        believes that there is high risk involved with such.

     3/ LargeISP knows that if they don't peer with SmallISP, their
        customers won't care.  LargeISP knows that if SmallISP can't
        get traffic to LargeISP, they will have a poor service.
        LargeISP knows SmallISP will then/therefore buy
        peering/transit (prolly from them).  [this perpetuates the
        small number of global palyers model]

  I don't see that this is necessarily "correct" justification, but
  it is justification.
