I presume his logic is that it will be cheaper to have government run healthcare because of all the the 'costs' that occur from being uninsured and sick. Basically, it's in the state's interest to have as many people healthy and being productive. It's not altruistic in any way. It's just better for the state to have a healthy population, especially if we needed to conscript an army (why else do you think obesity and smoking are constantly problems?)
I don't know if it will work though, but that's my take on how it could possibly make sense. Of course I'm assuming that those who get sick and/or have injuries and do not seek treatment only because they don't have insurance.
