Generally the problem with just doing that is power.  Network operators
don't want users to have the power to do whatever they want, for
security or financial reasons.  There are also some middlebox functions
which make more sense when use is aggregated.

In that case the first-hop router is then a middlebox.  (I tried to get
people to use "middlefunction" for a while to get away from the "box"
preconception, but even I didn't like it.)
