eBGP multihop carries with it the implicit possiblity
of session highjacking - in a normal (Multihop=1)
session, the router would not be able to find a
duplicate neighbor with the specified IP address
directly connected.  Obviously, once you're saying
that the neighbor could be anywhere in the world,
what's to prevent me assigning my home Macintosh with
a second IP address and injecting whatever I want into
your network?

Just because you assign that second IP address to your Mac does not mean
that anyone else in the world is going to see that announcement, which, in
turn, would not let you to hi-jack the session.
