Well if you choose not to exercise your right to a swift and speedy trial you're not signing a registry saying you will never exercise the right in future trials. The word waive does not necessarily imply permanent relinquishment, it only implies the voluntary nature of the relinquishment. Regardless of the word you choose to use for it, the point is that a swift and speedy trial is a right you have. There's nothing fundamentally illegal about a long trial taking place, you just can't force it upon someone. Slavery on the otherhand is explicitly forbidden. You can waive your right to freedom all day long, it doesn't make slavery any less illegal. > In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the Assistance of Counsel for his defense. > Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction. As for permitting someone to kill you, this falls very much into the same category of explicitly forbidden. Murder is illegal, and "he was asking for it" is not a valid defense. On the other hand, something like euthanasia, so long as you're in a jurisdiction that does not consider it murder, is permitted. In neither case is your right to live or lack thereof a question.
