title_body: At what point does drone insurance become worth it? Should the average enthusiast buy drone insurance?
  
  I'm expecting it to be essential for commercial use, or if the drone was used in a busy area, but what if the drone was a collaboration between multiple people?
upvoted_answer: This is a personal approach, so like all financial advice it's only worth what you paid for it.
  If you have worked with the insurance industry in the past, you will likely have learned that good insurance companies pay out almost (if not more) money than they take in. This is because what the insurer is doing is taking the premiums and lending them out, much like a bank. So when you spend \$100/yr across 10 years, and you get back a $1000 payout in the tenth year, the entire time the insurance company has been earning interest on the money you gave them. This 5-10% overhead is quite profitable when you have tens and hundreds of billions of dollars stockpiled.
  The upshot is that insurance won't save you any money in the long-term, it only spreads the financial pressure of a decision across time. I only consider insurance worthwhile when the cost of throwing my hands up and walking away is unacceptably high. Put another way, I only get insurance when either required by contract or law (e.g. renters insurance or auto insurance), or when I cannot afford the consequences of not having the thing which is insured.
  
  Worthwhile: I have a pet, and I don't want to have a financial consideration enter into whether life-saving surgery is an option.
  Not worthwhile: I have a television which I don't really watch and wouldn't miss it if it weren't there anymore.
  
  You'll have to decide for yourself the impact of losing your drone. If it's just a toy and you don't think you'll fly it again if you lose it, then maybe it's not worth the cost of insurance. If it's your livelihood and you can't afford to buy another one then insurance is a guarantee against catastrophic business failure.
  Or if the amount of damage you could do with your drone could cause you to be personally liable for a ruinous amount, then you might want to protect yourself with insurance.
  P.S. Drop a comment when you decide, I'd love to know how your reasoning went.
