"Without property, there is no identity or freedom"

"Every man has a property in it's own person"
John Lock

You own yourself, you are your own property. You determine your own destiny. So freedom and property are on the same side of the coin. If you create something within your own means, that is also your property. So you own the fruits of your own labour.

You have to protect property rights else freedom cannot exist.

It protects freedom of press, religion or against slavery.
