Most people I've known prefer good health because it feels good and wouldn't need to cite lack of insurance, dishonest insurer, etc. as reasons to maintain it.

I think that's a misinterpretation of the article.

Or simple contraposition :-P

Please correct me if I am wrong, but if the relevant part of the article is "I do not have insurance, so it is important that I maintain my health", then the contraposition would be "It is not important that I maintain my health, so it follows that I have insurance." What you are suggesting as the contraposition is "I have insurance, so it is not important that I maintain my health", which is the inverse of the statement (and equivalent to the converse "If it is important that I maintain my health, then I do not have insurance."

Ideally, yes, you shouldn't need the specter of something like lack of insurance to motivate you to pursue a healthy lifestyle. That said, nobody's perfect. It's still a valid reason, even if it shouldn't be a primary reason.
