I think I am in big trouble now because one year ago, as I prepared to move to Florida, I did not want to use either of my home state health insurance plans when a potentially minor symptom developed (resting heart rate changed from 55-60 to 70-75).
Also, I could not apply for Florida insurance and then immediately start seeing doctors there (pre-existing condition limits). So I was in limbo (still felt perfectly good and seemed healthy), as I went back and forth to Florida over a six month period, getting things set up there. I did not officially change my home state residence, in order to maintain my health insurance here. Then I started feeling worse, had to see home state doctors, and now, because of the delay, I may not live very long. My fault, yes, but if we had universally available health insurance I would have seen a doctor when I first noted something abnormal (as I mentioned to friends at the time), and then I might have been able to live a full life.
It is immoral for the wealthiest country in the world not to provide a guaranteed level of healthcare for all citizens (not just emergency care).
Note, I am under 40, have consistently averaged $80-100k annually trading, and have always paid $300-$400 per month for health insurance (usually duplicate coverage), but because neither of the plans that I had transfer to other states, I wanted to hold off on pursuing what at first seemed minor, because even seeing the doctor for a minor problem can make it much harder to get new health insurance (and if you have something bad, then they will not insure you, or they will exclude anything potentially related to that problem). You also cannot lie to get insurance, because then they can cancel the policy later when you need it.
Ironically, until three years ago, my "backup" health insurance plan (that I had through my undergraduate alumni association) would have been transferable to another state. That was my second policy for nearly 2 years, just for peace of mind and because I was thinking about moving. However, when the insurance company (U.S. Life) started to have some claims from the group (not from me), they just cancelled the whole policy for everyone. It is incredible to me that health insurance companies are not in business to provide "insurance" but rather solely to position themselves so as to make as much money as possible. How can you be certain that your health insurance company will still have a policy for you in five or ten years?
My advice: only buy insurance from big nonprofits - most state BCBS's and others like Kaiser. Unfortunately, these nonprofits' policies are usually only good within that state, so it is difficult to obtain similar coverage if you move, unless you are still healthy. Also, as I looked into the possibility of incorporating and trying to get a one person "group" health plan (with guaranteed coverage and lower premiums), I found that insurance companies are not obligated to offer such policies to one person groups.
