The recent discovery of the Higgs Boson Particle nearly 400 years after the death of the great discoverer of physics, Isaac Netwon, reminds us that we are constantly searching for and discovering scientific “laws” and building blocks.
There is another search and process of discovery a republic is supposed to be involved in as well. Over two hundred years after the beautiful Declaration of Independence declared certain truths to be “self evident” we are still supposed to be searching and properly discovering our “natural rights”. Just as “laws” of physics are constantly being discovered and tested, the “laws” that support our “natural rights” are also supposed to be discovered and tested.
We can only change the dynamics of a physical object with the application of force. Newtonian “laws” of motion tell us for instance that “Every object continues in its state of rest unless compelled to change that state by external forces acted upon it.” 
It is the application of force that changes the motion of an object. Likewise it is only through force that our “natural rights” are changed or violated. For example, as a human being you naturally wish to express yourself. We call this the “right” to freedom of speech. It is only through that application of force that you will be silenced. Remove the force and you will be free again to express yourself as you wish. The same goes for your desire to freely move, trade, associate with others, to worship, and to defend your self.
Notice that with “natural rights” it is only the application of an outside force that interrupts the “right”. It is outside force that violates your rights. However, there is nothing that necessitates an act by any other human to deliver the right, just as there is no requirement of force to allow an “object at rest” to remain at rest.
Ayn Rand has something to say about this in her book “Philosophy: Who Needs It.” 
“To deal with men by force is as impractical as to deal with nature by persuasion… It does not work and has not worked in any human society in history.”
Compare this to the idea of a recently discovered (within the last 100 years) “right” to healthcare or education. What do we have to do for the delivery of those “rights”. If we do nothing how could the healthcare or education be delivered? Obviously there is a contradiction somewhere.
The same is true for the very important freedom of trade. Trade is between two freely acting individual parties. Each side, impelled by rational self-interest, enters the trade. Each seeks to better their current condition with the completion of an agreed upon trade. Notice there is no third party in the transaction and no force other than the rational self-interest. Any uninvited entry by a third party would be a violation of the freedom of trade the first two people wish to exercise. Again it is only the application of an outside force that violates the rights of these individuals.
What happens with a system where government forces us to trade using only the “money” it creates? Our government takes control of what they designate as the only “money” printing machine in the country. Government then requires us, through the force of Legal Tender Laws, to use their “money”.
Where then is our freedom of trade?
Take a look at the charts on website I linked to below. Imagine how our lives would be different if the value of what we exchange was not undermined by the forceful “stabilization” schemes of our central government.

In the end it doesn’t really take imagination. It only takes the courage to set yourself and your fellow human beings free. Set us all free from the outside force of government that takes away our liberty, violates our rights, reduces our prosperity, and destroys our peace.
You really only need to do one thing. You just need to stop being afraid to let freedom win.
