No one has said that people should not be insured. No one said that accidents don't happen to people. In fact, I believe that single payer is the only solution to our problems, but that doesn't seem politically viable.
What was said was that the choice to be insured should be left to the individual. At certain points in people's life they may want to elect to go without insurance if they feel the time is right for them.
What was said was that the likelihood of a healthy 30 year old to require significant medical attention is small. Which it is and I provided nationwide evidence to illustrate so.
There are people in their 20's and 30's who do not have life insurance. Those who do not have a will. That is the choice they make because they know the likelihood of them needing it is small.

Having private insurance isn't the foolproof answer to protecting yourself anyways. As
3/4 of people that go bankrupt because of a medical bills HAD insurance at the time.
