You seem to be making my point not yours, opposite is not defined as a lack of,  or of not being something , see dictionary definition above.
Apathy or indifference is not opposing properties of love, it is a lack of.  For instance if two people are stood on opposite sides of the street and a person is stood in the middle, would you stretch the definition to mean that the person in the middle (neither one or the other) is on the opposite side of the street of both ?  

As for you other points the way you are applying them opposite of having £5 would to be in debt by £5. £5 is a definable sum.
Just as to push is not the opposite of not pushing or applying no force at all, the opposite to push is pull, to be an opposite it must have definable properties, otherwise how could you determine it was an opposite.  

We use a lack of something as references all the time in relating to physical objects, I'm just applying the same thing to mental constructs. Let me demonstrate by asking you a question. If I gave you $5 how much more would you have than you do now? You would be 5 dollars richer than what you had before. If you had nothing before than your point of reference is exactly the same what you have.

I would have £5 for sure but it's the having something that gives it meaning, not the previous lack of.  Not having the money would simply mean i had nothing, no meaning could be gained from saying that I had a previous deficit of £5, before I got the £5.

What you feel about something you don't know about has to be nothing by definition, agreed? Wouldn't that be a good baseline to measure emotion from?

I'm not sure what you mean by this to be honest, could you clarify ?
Are you asking if I have no previous knowledge or description of something, then I have no way to describe it, but by adding descriptors it will give me information i previously did not have and increase my knowledge and understanding ?
