I can just picture a news article posted to Somersoft which details how speculators are hoarding fresh fruit & veggies, doubling the price for consumers. Some here would be saying, "Well food may be a human right, but why do they need to eat fruit & vegetables when they can survive on two minute noodles or rice?".
Hobo, this analogy is as irrelevant as they come. You can't rent fruit and vegetables.
In your analogy, renting a house is equivalent to eating the fruit and vegetables. Owning a house is equivalent to owning the fruit and veg shop. The first is a relevant concern for humanity. The latter is of relatively little demonstrable benefit to society (it has some benefit but has nothing to do with human rights, where the former concern is most definitely directly relevant).
If anything, home ownership discourages mobility in the economy (eg we have massive youth unemployment in Tasmania at the same time as lots of jobs going begging in the Pilbara), particularly with stamp duty as high as it is. If you want to talk about addressing imbalances that are detrimental to society, stamp duty would have to top the list - it is a pure mobility tax. Right up there with payroll tax as one of the worst forms of taxation that can be imagined!
