Franky, I would make use of such resources if I were living in the city but sooner of later there will be harvesting conflicts and fights (i.e.; ‘I was here first’), vandalism and the inevitable regulatory/permitting process for citizens to be allowed to use this resource. There will also be the likely fruit picker-thrower teenage twerps.
Finally, clever immigrants will make effective use of the fruits and nuts once they adapt to them in their diets. In my old area, the Hmong had admirable harvesting skills and often found themselves in conflict with the law. This aspect is tailor made for bigotry and any conflict there will fuel the press and gub’mint types with outrage over our cultural hatred for the poor and oppressed and the dire need to oppress the rest of us, too.
On the whole, though, I'd say it's a good idea if they can care for the tender and delicate fruit trees with all the clods pawing them and damaging their branches, spurs and bark.
Speaking of Asians... I did see one case where publicly planted fruit trees - female gingko trees- had become a nuisance as the fruit from gingko smells like vomit and the whole park would smell liked it had been discovered by a horde of drunks after a hotdog eating contest. But fortunately for the trees, some local Korean wandering the park one day discovered them before the orders came to cut the trees dwon, and called in his family and friends to harvest and clean the fruit for the tasty nuts inside, and ever since the park manager simply calls the Koreans at harvest time and they glean the trees, no one the wiser. Trees saved. Nostrils unoffended. Koreans happily muching on gourmet nuts. Win win.
