Are you also against loans?
Insurance is just a way offload risk onto someone else for a fee. An insurance companies profits are not risk free, but they hope a large diverse pool of insured will keep them from being wiped out in a large event.
Most of us don't have a choice on whether to carry insurance or take out loans. I think it's more interesting to look at what the rich do, and from my reading it seems to be mixed depending on cost.
