Not mentioned in the letter is one of the key changes that came about through the ACA and which will disappear with it. Namely, the fact that individual health insurance policies were one-use coverage. Prior to the ACA, if anyone in my family developed a serious medical condition, we would be covered, up to the paltry lifetime limit, only for the rest of the policy life (one year). At that point, the policy would be canceled and we would be uninsurable. Along the way, we would also end up like most people with health issues, bankrupt. 

I will never understand what motivates people to want to have 40k people die from lack of access to health care. I suppose that's why I left the GOP when Reagan got elected. Even Nixon was ready to sign on to single-payer.
