The idea that government could _not_ be involved is nonsense. You simply don't perceive some government involvement as involvement because you take it for granted. The only question is where do you personally want to draw the line, and by what principles do we organise government involvement.

You probably don't want the government to stop being involved in securing your property or maintaining roads. None of the tech firms want the government to stop being involved in securing IP rights. Etc. etc. etc...
