The reason we have government in the first place is to deal with the risks of living in a free society. Outsourcing that job to private companies by mandating that citizens purchase insurance is a corruption of the social contract. If people are engaging in behavior that poses an unacceptable risk to others, then make that behavior illegal. Otherwise, leave them alone. If and when they harm someone else, hold them accountable. Prepaid punishment for crimes we may never commit is insane.
