Sorry but I think you are missing a lot.  The ACA was designed to take control of the private insurance market and not to fix anything. If the government controls your access to healthcare, they control you.  Obama expanded Medicaid to include anyone living at a certain percentage above the poverty level. It was originally designed for women and children.  Yes, Medicaid is a welfare plan.  Expand it if you must but do not destroy the private market insurance industry.  Do not force business to provide healthcare plans. It kills jobs because government doesn't guarantee profit margins.  
Obamacare forced people to buy a Healthcare policy.
 Many people wouldn't buy an insurance policy if their lives depended on it.  They don't understand the mechanics of an insurance policy.  The can't HANDLE the concept of spending a lot of money without the immediate satisfaction of getting something they can touch.  Republicans are no longer forcing them to buy insurance. They are free to choose.
