If you're FIRE, there's no need for life insurance. With 1 million in assets, you already have money for your dependents, and life insurance is not replacing your income if you're not earning anything.
Teenager should be out of the house and not need support in a few years anyway and and you have college expenses already figured out, and you don't need to pay for child care if spouse becomes a single parent.
Your wife works and makes enough on her own to support basic living expenses (30K is basic coverage in my area), so wouldn't need insurance to cover in that instance either since she could survive on her own without anything - but she has your nest egg in addition so literally no need to cover income/living expenses.
Unless you are very unhealthy, or drive/travel frequently enough to be a higher risk - then it sort of like you bought a lotto ticket that might stand a higher chance of paying out for "fun" money to your wife/kid. But that's all it is, and gambling is never really worth the cost in my opinion.
What does your wife think? If you both are in agreement, I'd ditch it. But if it helps her to sleep at night knowing there's a huge payout if she loses you, 1k might be worth the peace of mind for her.
