Peter Bos
From Wiki
Peter Bos, as far as I know, was the first person to propose that insurance companies could be a replacement for statist government.
I know that sounds ridiculous, but the modern insurance company is burdened by a great many rules and regulations that prevent it from providing as many services as it might otherwise be able to do.
I understand that Peter is writing a book on this subject.
Here's an article by Peter Bos about collectivism and individualism.
