The problem I imagine with it would be them falling back on the mental illness and mental incompetency card. Will they ever accept that someone can be of sound, rational mind and want to die?
Will they ever accept that some illnesses can't be cured to a reasonsble standard of living? Mental as well as physical?
Will they concede that some people are simply too expensive to maintain- if they are fit to work but don't want to and they want out of the system- will they let them leave? I kind of doubt it because it demonstrates that there are problems with the system.
Plus- if they bring in assisted suicide for all but additionally start cutting benefits- then I imagine you would get people dying to avoid a life in poverty when, they maybe would have lived if given support. Someone posted the other day about a homeless man using MAID even though he had told them he actually wanted to live! So- it starts to look more like social cleansing rather than something for the good of the people.
Have you watched Westworld III? (Spoiler alert here.) Why would a government plough lots of money and resources into a person that likely will want to kill themselves one day? They may even be able to hurry that along by not providing them with adequate help they need along the way.
What would happen if you gave everyone an alternative? I wonder just how many would take it. Would that start to screw up the economy? How many people want to spend their lives in a wage slave job? In a high pressured, specialist job like a doctor? Doctors have very high suicide rates. It's the people at the very top that get to make these decisions and we are basically chess pieces on a board to them.
I'm not saying any of this is right of course and I'd love the opportunity to be given assisted suicide. I'm just saying- looking at how this world is set up to run, firstly- it doesn't benefit those in power to let just anyone CTB. Plus, they could actually use it to start getting rid of undesirable members of society- the sick, the old, the criminal, the homeless. What incentive would there be to spend lots of money rehibilitating people? Getting them off of drugs? Getting them expensive treatment, housing, education? When- if they do nothing- they may be driven to want to kill themselves? I wouldn't put it past of governments to do that!
So basically what I'm saying is- theoretically-wise- it would be great if this could happen but in reality with how corrupt this world is- I think it becomes complicated.
