The NHS will be a winner, no health tourists, anyone coming to the UK will have to have medical insurance or no entry. Would you travel to America with no health insurance?
Most countries do not require medical insurance to obtain a visa. EU (Schengen countries) do require such insurance. Usually, for other countries it is optional. (and is different to normal travel insurance)
I have already explained that the EHIC scheme does not cover planned treatment. It may, in some cases, cover existing conditions.
So, please explain how and where these health tourists are coming from, and how they are abusing the system.
I think we can discount some EU citizens as health tourists as some EU countries provide better health care than the UK.
Currently, non-EU visitors do not need health insurance to obtain a UK visa, even though the UK is perfectly within their rights to request such assurance. and they would be harmonising with the rest of EU, if they did.
Why do you think the UK does not operate a health insurance scheme already for non-EU visitors?
Why do you think anything would change if we unilaterally withdraw from the EHIC scheme?
If the UK did withdraw from the scheme, how do you think it would affect EU tourism into the UK? And how would EU react?
Additionally, if we withdraw unilaterally from the scheme, how will it affect the multitude of pensioners living in Spain, France, etc.?
I notice that you ignored my first two questions:
So you think that because we don't operate the system the way it is supposed to be operated, we should unilaterally withdraw from it?
Who's fault is it that we don't operate the system properly?
