Savings based on what? Insurance is there to make money, it **cant** provide any savings on average unless it operates at a loss.
Now if you are talking about the savings that is created because insurance companies negotiate lower prices, that is the very thing outlawing insurance is intending to get rid of, to make sure the prices the average person gets is the same as the "real" price insurance gets. The fact that they scam you into insurance by charing individuals astronomically higher prices is the very thing that needs to be illegal.
