A single payer system, like all systems will be imperfect, but I still support it. If managed well it will provide basic quality healthcare for all. It will also cause chaos in the markets for those who already have insurance. Any major overhaul will cause a decrease in quality of healthcare for some and an increase in quality for others. Whatever we do will take 10-20 years in place before it becomes an efficient system. But since the current systems are so deeply flawed, it's a painful choice we will need to make eventually.
