Why would they do that? Even now, most private health insurance policies cover palliative and/or hospice care. I'm not sure how the ability to predict mortality with better precision would change that.

That seems like a loaded definition that necessarily implies that liberalism is good in some sense.

Either way, these definitions can mean different things and there isn’t one true way of defining them because they’re used in different ways — even in America.

Liberal and conservative are temporally relative terms in the context you’re using them. Conservatives try to conserve ideas and arguably that would include ideas like human rights, democracy, and federalism. Liberals try to push new ideas, or currently unpopular ideas, into the mainstream.
