The Difference between Liberal and Libertarian

What is the difference between libertarian and liberal?  This is a question I have been asking myself lately and I realize that both pursue right aggressively but there is a difference between the two.  A libertarian concept of rights are not founded on law as a legal permission but on property.  The thing that secures all individual rights is property and the government secures our individual rights when it resigns itself to the role of protecting property.  

A liberal (or conservative) might believe that rights are created by law but those rights end up stepping on the right of someone else.  In a natural setting that person may reject another person's request for something but under the force of law that person can not reject another person's demands.   This is why positive law violates the freedom of the individual since an individual somewhere will have their rights transferred to another person and when I say transferred they are redistributed to another.   

The law may require a parent to take care of there child until the age of eighteen but what if that was raised to twenty-eight?  The parent definitely would not accept that but the law removed the parent's choice.   What if the law was resigned to protecting the property and the right to transfer a person's property to another.  The parent then has the right to transfer their resources to the adult child and the law would protect the parents choice or their free-will.

Liberty of the individual was protected when the law protected property.  This is the difference between liberal and libertarian.  Libertarians see a person's rights belonging to them and is protected by securing their property with the force of law.
