The fatal flaw with this argument is the number of unnecessary deaths in Europe alone caused by the overwhelming of the health service during the first wave a result of government inaction.
Now there is a high rate of vaccination then restrictions are being removed in an organised manner which will allow the virus to circulate and natural immunity to grow without the deaths a “let it rip” policy would have sanctioned.
To say your health is not the responsibility of the government or NHS is a nonsense. Who pays for the “government” or the NHS? and what do you pay for?
