How can you possibly be surprised that people would insure a vehicle...car, aircraft, unmanned, etc.? Crashing your UAV and being out ~$1000 would negatively affect your future flying
Because 'saving' $1000 by filing a claim means your insurers for auto & home have a reason to rase your rates and collect that loss through higher premiums. Filing a claim is equivalent to having an auto accident. If you've been with your insurer for a while, it probably won't affect your rates. But if you shop for lowest rates at renewal, you likely will no longer qualify for the best rates. The way I see it (especially with how I shop at every renewal), you can pay for the $1000 loss out of pocket now, or you can file a claim, and pay for it (and probably more) later through higher premiums.
