From the comments section of the original link:
1) Could not agree more. UK residents in the EU should be made liable for their health costs.
2) Well I have private insurance so you can knock one off that total, I actually don’t know anyone that doesn’t have private medical insurance, their own capital & pensions.
and from your link:
1) When you move to Spain, the first thing you have to do is obtain A NIE number. This will allow you to get your Residence Cerificate and if you are a pensioner, also to get registered on the Health system, Your SIP card. You will then be allocated a Doctor at a Health Clinic. The SIP card is then presented every time you need to see a Doctor. You will also need to change your English Driving Licence and if you have your English car with you get that registered in Spain also. Some people seem to want to make their life more difficult than need be, because they are trying to remain under the radar, as they may have something to hide. Don't get me wrong, living in Spain can sometimes be difficult but it is a learning curve and people should always be willing to embrace a new culture.
2)I understood from talking to expats in Spain, that what the EU health card got you, was not free health care, but the same health care as the locals, which is not free in quite a few EU countries.
