Choosing to "euthanize" yourself is something that is so predominately chosen in fits of mental illness that society has probably made the right choice in banning it outright. Further, I think there's a strong argument that
other people shouldn't be allowed to add any weight to the idea of killing you...
As someone else brought up, there can be disagreements between family and an individual about when the right time for them to die is in both directions. Even in America this can be observed with things like life support for the very elderly, an intervention that is sometimes necessary for continued life but not considered euthanasia to forego. You won't have to dig very deep to find a doctor that has seen families argue about this.
So, if you say "only I can make the decision," then mental illness becomes a lot more deadly than it has to be. If you say, "other people can weigh in," then what do you do when they want you to die more than you do (and start pressuring you, and you're old, and already depressed...)? This leaves us at our current state, which is "nobody gets to make the decision."
