No one is arguing people shouldn't be able to fight to live. In fact, the post you are responding to was only talking about if things are "worse than death".

But in general for the larger point, we should make sure that people can fight to live, but that assholes aren't stealing from them by selling magic beans.

You're displaying a serious lack of reading comprehension. End of life care provided by palliative specialists is completely different to "scammers who absorb so much cash that they prevent real cures from being researched" and "people who squander their family's financial future on magic beans in futile attempt to live, but die anyway".
