Patents themselves (using government to give one party a monopoly at the expense of all other parties) are against free market principles.
Which basically means free market died around 1474
We don't have a free market. I assumed that much was clear.
BTW, you having a cow gives you "a monopoly [on that cow] at the expense of all other parties," which is "against free market principles."
If you were able to patent cows in general, or "milking" as a process such that everyone else had to license "your" technology from you to be allowed to own and milk a cow then you would have a point.
