Free healthcare has far too many benefits that outweigh the small percent of the population that might abuse this new found medical freedom.
The medical world, since the beginning, has been dealing with this fear of the clinical and the motive that your health can have a punishing cost to maintain. Some people are so afraid of that cost that they would rather not seek medical help and suffer than be put into drowning debt.
People might argue that healthcare should only be for those who afford it, who can pay for the best of the best but that’s a very closed minded and entitled way to look at things. Free healthcare would allow for everyone to be able to be able to see doctors and undergo surgeries for whatever ails them. Medical attention for illnesses or medicines that help keep you functioning.
While there would be an increase of patients and doctors visits there would not be a real increase of those with ailments. The only thing that would change is people coming in when they actually need help or advice. This would decrease the amount of people spreading sickness and diseases. 
It would allow them to come in for smaller problems to better under their body and it’s own unique quirks.
Human beings are meant to learn from their mistakes, grow from their mistakes and not have their lives shortened by things out of their power like a sudden car accident. There are indeed risks that people should know better than to take but in the long run, when people need help they should have the means to be able to receive it with strings attached like a deal with the devil.
