The bottom line is this...
If you object to what the government can tell you what to eat, how much to exercise, what sports you can play, and so on, then you have no right to expect the government to take care of you, because by extension of that care, the government have every right to tell you what to eat, how much you must exercise, that you cannot engage in physically dangerous sports, and so on. After all, it is our collective tax money and wise investments of that money means we must do everything we can to reduce wastage, no ?
Ever done paragliding ? I would love to someday. But then what good does that do to me ? There is no health benefit in passively hanging under a parachute. But if there is an accident, I could be crippled for life and that you and others must pay to take care of me. Same thing with motorcycles. I am a biker. If I get into an accident, my injuries will be greater than if I was in a car. Therefore, the government have every right to forbid me from using the motorcycle. Must save as much money as possible.
I see the welfare state as the hypocritical state for reasons above.
You fail to see that we create an organisation which we give a task.
That is to ensure Healtcare is handled in an efficient way.
This organisation is separated from the government in our case.
The leadership is established in separate elections.
There might be individuals which subscribe to Your strange ideas,
but in order to implement them, they have to win an election,
where they propose such policies.
Why do You think they would win such elections?
So far, there are no restrictions on what You eat, how much exercise,
restriction on dangerous sports, paragliding, biking etc., and the system still seems to work.
Instead, the system focuses on removing reasons for danger, like requiring
everyone to wear seatbelts while travelling a car. Kids bicycling must wear a helmet etc.
Motorbikes (and cars) have to go through an inspection every year to ensure they are safe.
You are describing an 1984ish Big Brother society which is not neccessary
for a Welfare state, and is probably acting against the well-beeing of citizens,
since noone likes to be ordered about.
