I lived that way for a lot of years. Figured things out on spreadsheets, comparing premiums to potential losses. Only bought the insurance that was required for the cars, dropped everything else. House was a gamble, but the rates were/are all based on some pie in the sky McMansion false guesstimate of 'replacement cost' that is 2-3 times what is realistic.
Then prices on even simple things started getting stupid. Lumber is silly high. Even simple things like copper wire have gone nuts. Hardware, nails, screws .. $9/box? We've already done the medical costs threads. The greedy overlords have priced the people out of being able to afford the basics and then hiked insurance prices to obscene levels. That wasn't enough to rip us off, so they imposed unreasonable exceptions and exemptions to covered items.
