Whilst I fully agree with your sentiments Stoop, I think the big problem is that, as things stand, no insurers are willing to offer the level of cover that is currently being demanded. Not at any price.
Therefore, people over 70 who are more than willing to pay for insurance cover, or who have the financial means to pay for any medical needs as they go are, in effect, going to be exiled without any option to stay whatsoever. That, I think, is a very harsh indeed.
