Things I Don't Understand: objecting to assisted dying when you don't mind if people die

This post was inspired by, but is not directly related to, this op-ed outlining how the new provincial government's policies could kill people.

Policy can kill people.  Politicians who enact such policies and other proponents of these policies either don't care if people die, or see people's deaths as acceptable collateral damage.

What's weird is the intersection between not caring if one's policies kill people, but being opposed to medically-assisted death. If you don't care if people die, why would you object to people dying?

Some people hold the idea that people should contribute to society rather than being a burden to society.  Others refute argue against this idea, saying that your value comes from who you are as a person rather than what you can contribute.  (I actually don't hold either of these ideas - I don't feel it's my - or anyone's - jurisdiction to go around insisting others contribute to my satisfaction or accusing others of being a burden, but I also don't feel that every human being has intrinsic value for the simple reason that I can't perceive any intrinsic value in my own essential humanity.)

So I also find it weird when people who hold the "contribute to society or you're a burden" idea are opposed to assisted death. In a paradigm where it is possible for a person to be a burden, why would you be opposed to someone saying "I'm too much of a burden, so I'm going to get out of the way now.

One reason I have heard for objecting to medically-assisted death while not objecting to death itself is that if you can do it yourself, you don't need medical assistance.

But the benefit of medically-assisted death rather than suicide is it doesn't leave a mess for other people to clean up.  Currently, we don't have any non-medical method of suicide that doesn't leave a carcass in a place where it's inconvenient to others for there to be a carcass.

In contrast, in medical settings where people die, they're fully trained and prepared to move a dead body and hygienically clean up afterwards. (In my grandmother's long-term care home, they have whole procedures in place for this eventuality!) Until we have Suicide Place, medical contexts are our only option for people to die without being an undue burden upon others.

So it's really strange to me that people who don't mind that their policies might kill people are opposed to people choosing to die.
