Could someone explain to me how a Free Market Non Govt intervention solution could either work or fail?
It all depends on what "work" and "fail" mean to you.
It's somewhat of a complex scenario to write out.
End the legal tender laws. End the regulatory system. Let wages rise and fall with the demand of said labor. End the IRS. Encourage competition.
The products here afforded more cheaply through the various means of a free market, including the products afforded more cheaply by way of the sun, soil richness, or other natural occurrence, are in no way a hindrance to individual wealth.
First, people are inherently endowed with the right to move freely. You own your body, and your actions/movements are your right to do so long as no one else is legitimately transgressed against.
The products/services becoming cheaper are not an ill effect thrust upon society. It is a positive for society or rather, as I care, to the individual. The common misconception is looking at things through a cost to the producer's lens rather than looking at things through a benefit to the consumer's.
Free trade promotes job creation, where it is warranted. Government protectionism promotes moral hazard and waste. They are not wise enough to dictate this or that to an infinitely variable economy. They cause harm (to all, though more importantly to those who wish to conduct their business as they see fit).
A[n actual] market for labor and a repealing of the legal tender laws would do the average worker much good. This is problems compounding problems.
