Dunedain policy vis-a-vis hobbits: wise or flawed?

[Tuor of Gondolin]

And a complicating factor in any isolationist policy regarding hobbits is the use of
the road through the Shire by dwarves (and elves). Short of putting in a bypass
north there would still be significant contact, especially for hobbits going to Bree, and a growing mannish population north of the hobbits could lead to resentment
about not being allowed to pass through the Shire. So wouldn't the ban have to be logically extended to dwarves? But then, if Aragorn recalled family history he'd know that dwarves can get rather testy and might not care to add distance to
their journeys by having to detour in their travels, going north or south of the
Shire to travel on the East-West road. Did dwarves stop at the Green Dragon?
One would presume so. (I can lick any four hobbits in this room, hick!)

Also, there was an ongoing hobbit relationship with the wider world, Merry and
Pippin going back and forth to Gondor, one of Sam's daughters being a lady-
in-waiting, and, presumably, hobbit reading of the Red Book sparking a
continued interest in the wider world. How about travel tours to Erebor,
Fangorn, Parth Galen, and the Pelennor Fields?
