I recommend you think about this: where does property come from? Is something ours because the government says it's ours or does it have a deeper meaning that transcends government?
I'd argue that property exists because things (apples, cars, gym equipment) have limitations on their use. If I eat an apple, you can't. If you grow a crop on this property, you can't. While he uses this gym equipment, they can't.
Even in historical contexts where there has been no effective government (silk road, dark ages iceland), ideas of property have evolved that are strikingly consistent, because it extends from realities of the world.
As states developed, they came to give stronger definition to property law. But then people who were well-connected to government decided that it would be a good idea to extend these convenient powers to things which were not property, sometimes by falsely labeling them as property.
So it comes down to who has control over the language.
Is property a distinct idea, or is it just a bundle of whatever rights the government of the day declares it to be.
And if you choose the latter, if the government says that black is white, is it so?
