This is mad (especially from a UK perspective!) and it doesn't cover the key point of insurance: you insure risks that you couldn't afford if they went wrong.
I insure my house, my life and my car because it'd be financial ruin for me and my partner if the worst case scenario happened to any of those. Sure, I could avoid going through insurance for small things and negotiate with 3rd parties to get bills down, but that wouldn't make a difference to a £500k house rebuilding cost, car crash settlement, or medical bill.
Similarly, if something went wrong then I couldn't go back and insure that risk afterwards! You can't insure unpredictable events as and when you need them, and there's no point in my organising insurance from the wreckage of my car, house or health.
