You could be sufficiently proximate but there is no loss involved
For example, it could be argued that I am your legal neighbour but given that you are not likely to suffer loss as a result of my actions and our proximity, then there is no cause for action
Equally, there could be reasonably foreseeable loss involved when I observe you a third party taking action that I consider ill-advised but if we’re not legal neighbours then there’s no cause for action against me
