Factor in no new EU staff after free movement is gone and the NHS, if it survives, will end up having to rely on more nurses from countries like Jamaica, Philippines, etc. So the issue that most leavers have, too many foreigners, isn't addressed at all.
All you do end up with is people who come from a entirely different healthcare system, don't have as firm a grasp of the English language and an increasingly poor healthcare system that will continue to struggle until even people who would be dead without it demand change, even if that change comes in the form of private healthcare.
So basically, the NHS was nice while it lasted. Helped to keep my parents alive long after they should have been dead...I'll remember it fondly.
