Is life hard?

So you're saying that people shouldn't get to have this right because of people with puritanical moral codes who cannot resist interfering in the affairs of others? They have to suffer because your puritanical Catholic sensibilities would be offended otherwise? Pretty much the same rationale that was always used to justify prohibiting pornography, sex outside of marriage, homosexuality, and the whole gamut. What if the suicidal person just went to a veterinarian and paid for Nembutal, not involving the state except for the fact that the state didn't have laws on the books based on religious delusions - why should that not be allowed? If suicide were legally above board and accessible through the state, then that would surely mean that one's family and friends wouldn't be able to have someone imprisoned just for having the wrong philosophy. I personally wouldn't mind all that much if I had to keep the secret to myself (because I wouldn't want anyone trying to exercise coercion over me), but the point is whether others would have the right to exercise violence, or call up authorities to exercise violence in order to prevent someone from dying through their own choice.

And you've still failed to justify how you can ever be harming someone by assisting them to die peaceful, at that person's request, and there's no kind of afterlife in which they're going to be regretting their decision.
