Your right, insurance markets have appeared for many things. I'm not sure why you think that's evidence against my argument. I cited an example where they did not, where the free market did not come up with a solution.
Your argument amounts to an article of faith. "The free market solves all problems, because if we let it, it would find a way." The crux of your comment when given an example where there was no such solution was to repeat your article of faith.
Just because the marketplace didn't do something 100 years ago doesn't mean that it never would. Obviously, there wasn't a need for such a thing, so what problem is being solved here? You just contrived some set of circumstances that you believe fits your hypothesis; in no way is this a reflection on the free market's capabilities.
It's not contrived, it's an actual problem that existed for centuries coinciding with insurance markets during which the free market did not provide a solution. Saying there wasn't a need for the thing because the free market didn't provide a solution is tautological.
If centuries is an acceptable time scale for obtaining a solution, then we're not really arguing about the same thing at all. I'm sure we could both come up with theoretical free market solutions to just about any issue. The problem is they don't always materialize, and it's not terribly difficult to see any number of issues in history that existed before widespread regulation that were not solved by the free market.
