Let's try to make this concrete.

Suppose I choose CI, and pay up now for a lifetime membership. I will pay $1250 once, and in parallel build up $200K insurance policy designating CI as the beneficiary. The only part of the money CI sees now is the $1.2K. No small sum, but neither it is more than a tiny fraction of the salaries and costs CI verifiably pays.

At 40, I can reasonably expect to go 30 to 40 years before I die. At any time during this period, if it becomes apparent that CI is up to anything screwy, I can (so I understand) change my insurance policy back; or at any rate contest their claim to it.

If you want to defraud customers, there are quicker, cheaper, more reliable ways to do it.
