Yes. I would not want to stretch the principle any further. To expect anyone to respect other people's needs as if they were one's one is quite unrealistic and, be honest to yourself please, nobody really does it. Neither do we love (or treat) other people the same way we treat ourselves nor do we love our enemies. Not only do we not behave this way, it is also highly unlikely that the human race ever will.
I assume human beings are essentially biological creatures, while they socialise for their own benefit they always compete for scarce resources. Evolution, history, civilsation, the development of societies and nations are higly dependent on this principle. Human race would not be a successful lifeform on this planet without fight and competition. Within this context we never see other people's needs the same way we see ours. May I give some examples? Here I go:
Imagine you are in love with a certain girl (or woman). Others might share this desire. What do you do? Happily retreat? Expecting, hoping, waiting for another person to leave over his/her love? No. Of course not. Humans are not meant to behave like that and they do not.
Imagine you want to get promoted in your job, bigger office, more money, the more beatiful secretary. Do we not all know reality? What are people like?

I am sure that is is the only requirement that can be made seriously. This world and our life is not going to be fair, wishing or hoping for another, a better world is permitted but world is unlikely to unfold as anyone of us wishes. We might know that we dislike or disapprove wars and weapons, crime and fraud and many other things.
Those things will stay in this world, they are part of reality and there is a point for reality: It has managed to become real. You cannot replace the rules of reality with others, even if you know (or think to know) there might be better ways. World, life and society have neither been designed nor constructed and cannot be improved easily.
What is the relevance of those paragraphs? They are relevant because the rule cited here in this discussion must fail, it is not applicable. It might be possible to apply it within one's own family although my own experiences are different. People are individuals, they do have individual needs and desires, some people might even say that every person is special, although I do not agree. I can agree that there is a common set of needs and desires that everyone shares with everyone else. What is socially appropriate follows from the requirment that those needs and desires must be granted to all people.
I want to add that I feel opposed to being required to guess other people's needs and desires. I prefer needs and desires being kept private while a set of minimal requirements exists that everyone agreed to. The elements of that set are not hard to guess but easily visible. Not to steal, not to cheat, to do one's best in every situation... I am afraid that my understanding of socially appropriate behaviour does not extend far beyond that.
