Malpractice is a good item to compare.
We see that for most government employees -- a Doctor in Universal Healthcare is now just a government employee -- they enjoy qualified immunity. This is how you propose to do away with malpractice.
So, a person loses a loved one due to an incompetent government doctor -- which will be most of them after adjustments are made and time passes -- that doctor will never be held responsible for his/her malpractice.
But hey, it may or may not save the rest of the population a few hundred dollars a year in costs.
BTW, in order to keep costs down for the government (you know, those cost controls) people will have to be denied certain services, some of them even life saving services.
