Although I don't disagree with what you said, I have two major objections to the current state of gov't intervention:
1. The smattering of FHOG/FHB stamp duty exemptions do nothing other than push up property prices. In other words, they're inefficient and don't help the people they're intended to help.
2. Whilst I sympathise with the need to give people a nest-egg in retirement, the current system is actually overly generous to retirees, because their PPOR is not counted. This means the government is effectively subsidising the passing on of property from one generation to another - by paying people a very generous pension despite them owning a property. There is no justification for this, and it leads to all sorts of distortions.
