Suicide is currently effectively illegal. Thomas Szasz, a psychiatrist, wrote about thirty five books. He wrote books such as Psychiatric Slavery, Fatal Freedom: The Ethics and Politics of Suicide and Suicide Prohibition: The Shame of Medicine. Both aging and suicide are tragic. That does not mean that aging should be accepted as something that is inevitable nor that suicide is something that justifies using coercion and force on law abiding adults.
It seems that SENS technologies are not desirable if suicide is not effectively legal. It is civil commitment and psychiatric holds that effectively outlaw suicides. Hopefully aging will be stopped sooner rather than later. Hopefully suicide will be effectively legal sooner rather than later. It is unfortunate that so many individuals support using coercion and force against law abiding adults. It is not morally correct to use coercion and force on adults who attempt suicide or are intent on engaging in suicide.
SENS technologies are only desirable if suicide is not effectively illegal. Suicide is tragic. However, only persuasion and kindness should be used stop adults from engaging in suicide in private. Of course, public suicide should not be legal, just like it is not legal to have intimate relations in public.
Hopefully all humans on Earth can live long lives of abundance, peace, prosperity, joy, bliss and elation. Hopefully no humans will want to engage in suicide. Hopefully all humans will be able to create lives worth living for their own selves. Hopefully more individuals will realize that aging should be stopped and reversed and that suicide should be effectively legal, at least for adults.
