The point was that it is a lot more complex than simply adding a route 
to the device instead of to the nexthop.
Let's remember that ethernet is by nature a broadcast medium and if you 
want it to behave like a point-to-point link you will have to be 
careful. Adding static arp entries has some drawbacks which you do not 
have on real point-to-point links.
In the end you are still trying to let a broadcast medium behave like a 
point-to-point link. Nothing more and nothing less.
