This would be absolutely devastating to most people in America (and the world). Being able to tank a $25k loss without any insurance help is a very privileged position.
I don't have a point of contention with your comment. I just wanted to make that observation, because I think it can be easy for many of us to forget it.
If you feel overwhelmed by the prospect of purging, try doing it a piece at a time. Even make a game of it: when you get dressed in the morning, you also need to pick an item. That item goes into a box near your front door.
When the box is full, go donate it, burn it in the back yard, what-have-you.
I had it happen once in a move: At 23, all my possessions got squeezed into 6 packages (5 of which were media mail), a bookbag, and a checked luggage. Everything else got thrown out or given away. I'd been living in a furnished room. At the new location, the only thing I needed to replace was a computer monitor.
Toiletries and soaps. Towels and washcloths. The shower caddy and the shower curtain. The plunger. The cleaners under the sink. The books on the back of the toilet.
Now do the same calculation in your kitchen, your bedroom, your family room. The couch, those chairs, a TV, your mattress and box spring and bedsheets and blankets, dishes and glassware and silverware, pots and pans, and so on. Even if you own cheap stuff, that all adds up very quickly into a loss most people can't readily absorb, even when you factor out the pile of stuff you don't wear any more and really ought to donate. I think we could inventory a lower/middle-income renter's belongings and spend $25K pretty easily.
Moral hazard and adverse selection are real issues insurance faces: that being covered makes the insured more reckless, and that people with higher risk self-select to sign up for insurance.
OTOH, insurance companies make more money the less claims they pay.
In general, we want to run our lives like people instead of like miniature conglomerates. Peoples' tendency not to want to live like automata is not the problem: the problem is the system they are trapped in which forces them to live as automata.
Water damage due to a sudden burst of a pipe. Required expensive drying of walls, replacement of part of the drywall and replacement of the flooring. Dealing with insurance was extremely pleasant.
Burglary of house. Lost laptops, camera, time machine, diamond earrings. Similar experience. Surpringly, the rule was: if you want to be reimbursed in cash, you get the current value (which is close to zero for a 6 year laptop). But if you buy a new laptop, you get the original purchase price reimbursed. “Hello new MacBookPro!” Zero complaints about the insurance.
Wow! How much was the replacement cost for that?
