In some important ways it absolutely can be, and the emergency exit doesn't help.

If I die, life insurance pays out. If I commit suicide, it doesn't.

If I die, there are some basic optional-but-socially-mandatory costs around disposal of the corpse and a memorial ceremony. Those are fixed and measured in thousands, not tens or hundreds of thousands. My property and assets pass to my heirs. They are grieving but financially secure.

Prolonged illness can sap my reserves dry and drain me of wealth in a manner matched only by the retirement home industry. My family can watch me suffer and wilt away while watching their potential financial security drip through a hose into my veins.
