Ignoring the issue of inheritance/what's fair/what's enough/etc.
And yes, I get that if you have a slow, lingering illness such as dementia then you'd end up paying whereas those who die from a relatively short-lived disease wouldn't (or not to the same extent), but that really is one of life's many unfairnesses
One of life's unfairnesses?
I don't want to live in a society that financially penalises people who are unlucky. That completely undermines the basis of a welfare state.
If we recognise that people can require state support by dint of circumstances (in this case, health) entirely beyond their control, we need to decide, as a society, whether we pay for that support or not. The former is my political position; the latter is something I suspect only a hardcore psychopath would assert.
What kind of person can say "Yes, bad luck old chap, should have got cancer instead, huh, the NHS would have paid for all of that".
The discrimination between hospital-based and home-based care is by far my biggest problem with this issue. I don't see there should be any discrimination. It worries me that by blurring this particular line with a move which for many seems somehow intuitive (?!?), there becomes less of a problem in twenty years time when the next suggestion is those with cancer - or, if you like, a proper illness (sarcastic italics) - stump up for their own care.
