OSM wants to record what is there on the ground. That is our mission. If you delete something from OSM that is there on the ground, then you are acting against our mission.

Of course deletions are possible, and even desired, if something in OSM is wrong, or if something that was there on the ground earlier is now removed. 

If you can show that the aerial imagery we have for this area is outdated, and that the track has been dug up and trees have been planted there, and the buildings on the north end of the track are now unreachable by vehicle but only from the water side, then of course it is a good thing to delete the track. 

But you cannot delete the track just because it is illegal or because you would prefer people not to know about it.
