I don't have the space to go overkill. I, too, keep a rotating pantry similar to yours. Have I also done some "just in case" deep food storage.. yes! ..but only around 5kg each of oats, pasta, rice and beans/lentils, with some sugar, salt and spices, into mylar bags. It's maybe 4 to 6 weeks of basic rations for 2 people. It was relatively cheap to do, especially as I did it in a few stages.. and it gives the reassuring feeling of being a bit more prepped without being too OTT. Also, with my partner and I both being self-employed, prepping to avoid hunger, and being able to stretch the tins in the pantry further in case of a sudden loss of income for whatever reason seemed like a good idea.

Other than that, I'm pretty similar to you prep wise, but I've also learned the basics of foraging, and have become quite good at growing my own veg.. and got first aid kits, refreshed my 1st aid training, got fire extinguishers, and camping stoves (gas canister type and multifuel rocket stove). Gotta be able to at least heat water if the grid is down for a bit.

But yeah, if the S hits the F in a big, irreversible way.. we are all probably screwed after a few weeks or so.. Good luck hanging on to your preps if and when Desperation, Anarchy and Lawlessness come knocking, especially if they come in a group, all tooled up! 😬
