> The industry is well regulated and ensures margins aren’t indulgent. Home insurance, auto insurance are often very competitive. But these days it's common when you buy a TV, phone, laptop, that the checkout button online also offers "insurance". I see the same renting a vacation home, offer for a cancellation insurance. Sure, it sucks if I'm sick and need to cancel my vacation and I can't get my money back -- but insuring against such events is often a bad idea. There is a lot of unnecessary "insurances" being offered to consumers today. For the record: health, home, auto, travel, disability, and generic liability insurances is usually a necessity. What author is saying is don't insure against spilled milk, even if many shops offer these easy add-on "insurances" at checkout. Personally, I sometimes find it hard to know what I should and should buy when renting a vacation home or car. I don't care for the cancellation insurance, but I do want a liability insurance (which most always include automatically, at-least where I live).
