It's nonsense anyway. Everyone could be living an ideally healthy lifestyle but everyone is eventually going to start failing regardless, as an inevitable consequence of the degenerative aging process. Cancer, heart attacks, stroke, diabetes, etc. will still exist. People will still be born with genetic illnesses. Communicable diseases and viruses will still exist. Car crashes, home and workplace accidents, fires, drowings, etc. will still exist.
The only way anyone will not be dependent on healthcare at some point in their lives is if they happen to be stuck down dead one day through an accident or unforeseen health condition. If people were to accept this fact then they'd realise the most efficient and practical thing to do is to provide healthcare the same way we provide other essential infrastructure, i.e. as a universal, taxpayer funded service.
