"We are going round in circles, you clearly don't see the issue & how it is a subsidy."
I clearly see your issue, it's that I don't believe what you are presenting is factual nor do I agree with your opinion and the impact it will have.
If I don't have a negatively geared property, but I work and at tax time I have genuine expenses that I claim against my tax, I get a refund for paying too much tax.
It is not a subsidy!
If I negative gear a proper, I have income and expenses, if I get a refund it's because I have paid too much tax, I get a refund.
