Even the world's crappiest healthcare plan protects against the worst case. I know - I had a major health event at age 29, and I had absolutely garbage insurance. $350,000 in hospital bills later, with approximately only $7k out of pocket, I was all fixed up (as well as current medical tech allows, at least) and my heart was a click-click-clicking away. Insurance with deductibles in that range for a single (and ~double that for a family) is really relatively cheap.
