Garrisons away from home

This is really to get the opinion of general members of the community on a principle

We have a member who has no grapes within hundreds of squares of his cities. Consequently if he wants grapes, he has to send cotters on long distance jaunts to get them.

To avoid being bumped, he has garrisoned a particular grape harvesting square which is many hundreds of squares from his city.

A member of another alliance, approximately 20 squares away from these grapes, who had not garrisoned this particular square but has harvested it in the past, now has taken umbrage and wants the garrison removed.

The question in principle is:-

Does someone have a call to ownership of a square due to the fact it is close to him and very distant from someone else who would like to harvest it. If so, at what distance can that right to ownership be called. 10 sq, 20, 50, whoever is closest or whoever is strongest?

Distances here are irrelevent IMHO, it makes no difference whatsoever whether one player is from 30 tiles away or from 300 or 3000, the relevant part of this is how far from the players city the garrison was set up.....anything over 10 is widely considered totally acceptable in uncrowded areas ...and in this case, as its more than double that it conforms more than adequately to every other alliances' written or implied stance on this. 

fair fights... LOL

Occupations of grapes or rare herbs without good reasons are hostile.  Good reasons include the protection of almost depleted herbs, the protection of gatherers at work, and claiming sov.  Some rare herbs are always almost depleted, they would die if only four herbalists without a clue harvest.
