That is correct, but disability insurance is far more important than life insurance.
If you die, your spouse can marry again, your kids will be able to work at some point and so on, there are no additional costs. If you're disabled, it becomes a massive, long-term, cost burden.
You obviously have no concept of marriage or the cost of an education for your kids. Life insurance is there to make sure your families life isn't utterly ruined. Your suggestion is to leave the spouse forced to marry someone rich fast and have the kids work at McDonalds.
And where exactly did I propose not having life insurance? Would you mind copying and pasting the text here?
If you have to choose between disability and life insurance, go with disability insurance. If you have enough money to pay for both, pay for a lot of disability insurance and some life insurance. Probably 10-20 times more disability than life.
