Many of us do follow the logic to its necessary conclusion. We don't assume criminals will magically disappear, we just would like law and order to be provided by the free market. See below before you dismiss it as impossible. http://faculty.msb.edu/hasnasj/GTWebSite/MythWeb.htm Edit: And I apologize for the background of that link!
A marketized law and order system would not solve any of the current problems with corruption. Perhaps you have heard the term "hired gun" or "mercenary". As always, the flow of money would still allow corruption, and those with money and no scruples would influence the law to protect themselves. For the mots part, that article was tldr, but I skipped down to find his discussion of this free market law, it's...mediat…
The first half of the article addresses the fact that it is impossible for the law to be objective. This is an extremely interesting idea in my opinion so I would encourage onlookers to check it out even if you are solidly convinced that free market law could never work. It's a bit hard to summarize the article so don't accept qdog's TL;DR at face value without reading it yourself.
My TL;DR, quoting from the article's conclusion: "The fact is that there is no such thing as a government of law and not people. The law is an amalgam of contradictory rules and counter-rules expressed in inherently vague language that can yield a legitimate legal argument for any desired conclusion. For this reason, as long as the law remains a state monopoly, it will always reflect the political ideology of those invested with decisionmaking power. Like it or not, we are faced with only two choices. We can continue the ideological power struggle for control of the law in which the group that gains dominance is empowered to impose its will on the rest of society, or we can end the monopoly."
