>>512583288 (OP)Maybe the prerequisite should be a final expression. Everyone has to create a masterpiece (subjectively, not everyone has skill or talent) before they are allowed to use the pod.
Most will choose to write a novel or a poem, some may paint their heart onto a canvas. Those incapable of movement could sing or dictate their finest theorem and those who cannot could blink at the letters on an alphabet chart until their work is complete, even if that work consists of "it hurts" enough to fill a page.
If you truly want to die, gift your potential to the world first. If you look at your completed work and decide it's not good enough, stick around and try again until you're satisfied. It's not a cruel requirement, but it will prove intent. If you're serious about suicide, you'll put every effort into your final triumph.
Earn your death through greatness.
