The Victoria's Secret founder jumped off the golden gate bridge like the rest of the plebians. I think suicide is the great leveler. Public infrastructure FTW.
In seriousness, if I had millions to spend on my death I think I would stage some kind of Battle Royale style game. Think the movie バトル・ロワイアル only more voluntary and instead of being cast entirely with photogenic Japanese high school students it would be primarily SS incels.
Basically I would rent an island. Recruit a bunch of suicidal individuals who have nothing to lose and want to die in an elaborate crazy way.
Stage a Battle Royale match whereby we are unleashed to kill each other off. All filmed for posterity. The advantage to the standard SN or N methods would be that you wouldn't have to kill yourself, eventually someone would do it for you. However the karma would be neutral as everyone would already want to die and would have done it themselves eventually anyway. You could even argue that the participants could accrue positive karma assuming that the universe favors death match spectacle over people going out with a whimper and vomiting ala SN.
People would be equipped with syringes preloaded with morphine at lethal concentrations. So if you were wounded you could end things quickly. There would also be a drone circulating to off anyone who sent a distress signal. This would hopefully minimize the time people would spend wounded and dying. Plus suicidal people would probably favor headshots and other lethal types of attacks as per the golden rule.
The 'winner' could potentially be awarded a prize and not have to die, but that would be up to them. Maybe millions of dollars and the fame of winning a hunger games event and attendant opportunities to mate with attractive humans would provide enough of a life change to make them want to go on. At the very least wrestling with the inevitable PTSD would give them something to do.
The rest of us would be existing happily ever after, toasting each others' glorious deaths in Valhalla.
