Hardly anyone has assets of $10 million, so they do not have the assets to insure. Many people do not even have assets of $50k, so again, why would they need insurance? If they get a judgement against them for $50k, they are bankrupt. That's what bankruptcy laws are for.
If your life is worth $10 million, you need to be the one to insure it for $10 million. Not the working class person who has no assets.
I see forced purchases of insurance for people with nothing to insure as similar to debtor's prison. Obviously not as extreme, but the same concept.
