Because then your kids could forge a signature on a fake letter to get your inheritance money.<p>Because then companies that happen to profit from your death have an incentive to convince you that you should die, using manipulative advertising and marketing.<p>Because then people who are highly depressed might kill themselves with assistance from a doctor, when an alternate route could cure them.<p>Because then the doctor might forge evidence showing that you wanted to be killed and it could be hard for the police to track down.
