I don't think the two are mutually exclusive. There's nothing preventing a universal healthcare system, partially funded by higher taxes on "unhealthier" behaviours that cause a disproportionate burden on the system. Obviously there will always be some proportion of people who draw from the system without ever paying anything in taxes (i.e. long-term unemployed). That's the case with any form of welfare, though. If you're philosophically opposed to non-net-taxpayers deriving any form of government benefit, then I'm assuming you're a priori opposed to universal healthcare.
