No, because suicide is also an extremely dangerous option to other groups of people - some mental illnesses cause suicidal ideation, and people who suffer from them are often terrified in their moments of clarity of the possibility that they may actually do it in their moments of "insanity".

The vast majority of people who attempt suicide actually regret it afterwards, and have no deep desire to die. Making it hard to actually kill yourself is an extremely important safety net for these people, who outnumber the terminally ill who actually wish to die by a large margin.

Not to mention, people can be compelled to attempt suicide by social pressure, either in bullying or by family members who view them as a burden. Having to go through a neutral third party who can help make sure you actually deeply desire this step is critical to protect you from others.
