I did about 15 years ago. It woke me up. I now have a years' worth of food, 4600 watts of solar power, 2 sources of water and the hardware and ammo to protect it.
Also an old non-computerized Jeep, HAM radios, and a bunch of other stuff I hope I never need.
Wow, great prep. Nothing like that here.
You are so screwed.
Lights Out is a good read. Patriots for the truth. Enemies Foreign and Domestic for an eye opener and Unintended Consequences for a real truth teller.
Insurance expenditures. Nothing crazy about that.
