Firstly, you are correct about the owner/occupier stuff. That aspect of it isn't fair. All owners (or all dwellers) should pay the tax.
Now.
Don't give me any of these sob stories. All of the possible ways of increasing tax (indirect, direct, by usage) can produce a sob story. And your one is shite.
I can make the arguement for fairness/justness of the tax, just not infallibly (as taxation is an art, not a science). Firstly, I don't believe that the fact that mistakes have been made in the past mean that we shouldn't strive for a fair and economically justifiable tax system.
There are many aspects of this tax that are unclear. For instance, I don't think that your first point should apply (a person who directs his income towards his family home should pay more tax) given that I think it should apply to all owners of gaffs (and therfore filter to rent). I do think that somebody whould pay more tax if there area becomes more desirable...not sure of the problem with this one. Desirability is often driven by factors such as new transport links or the creation of new amenities.
And finally, I don't think that somebody who maintains their house should pay more tax, but is this really that going to make that much of a difference? Enough to go with a tax likely to depress the economy.
