They aren't expendable but the best way for them to avoid their personal risk from the virus is them minimising their own contact with everybody else. And yes, I do think the authorities should help them do it by delivering food, medicines etc to them so they don't need to go out so much.
Trying to protect the sick by shutting down the country is going to cause carnage, and the fallout from that will be worse than the virus.
Due to being born with a condition that this year got me placed in a "high risk group", hasn't stopped me from working nor being physically active. 250 miles commute to and from work(4 day weekend, split shifts). It's something that has in the past had people crossing the road to avoid catching it from me. Forget all about the two metre distancing.
You'd seldom see it, or the effects. So do not label me or people like me as " sick".
I have seen the effects of drink, self inflicted injuries in my book, in many A&E's. Even there they seem to feel that what everyone else there has to do, isn't for them.
I'm upright and mobile, there's many who aren't. Why should I deny them the help and support they may require, if I can do many things for myself?
I'll also ask, how are you expecting "medicines" to be delivered. The procedure at present is the patient orders first. They do not appear out of thin air to be then delivered.
