I think you’re both correct, although you are addressing separate threat levels and emergencies (civil disobedience vs. natural disaster). I keep a basic bag, plus a small box with optionals that can be quickly loaded, depending on the threat. I realize this may take precious seconds, so this is time dependent. I live in the Chicago area, so civil unrest is a greater concern, and my firearms choice reflects this probable eventuality.
One thing that the article doesn’t reference is “How many people will there be in your Bug Out party?” The point being, that although there are some items that need to be in everyones B.O.B, there are others that don’t require duplication. Figuring out which items can be used by all the members of your party can reduce duplicating these items in each bag. For example, does everyone in your party need to carry a 1 quart backpacking pot, or will 1 or 2 suffice for your whole group? Those types of items can then be parceled out to the members of the group, and cut the weight down.
“Natural” brands of beef, turkey, etc. jerky do not contain any or as much of the harmful added ingredients seen in many commercial jerky brands. What is jerky? Jerky is a tasty form of dried meat. Dried meat, if you remember, is a long time proven survival food used by Native Americans and American pioneers alike, and also used by primitive tribes around the world. While these primitive tribes use smoking and sun drying methods to create “jerky”, today commercial methods of drying meat do this on a much larger scale. You have two choices: One is to buy the smaller serving packages, or to purchase your dried meat in bulk and have it shipped to you directly.
Size – Everyone overestimates how much they’re carrying when they go backpacking (if everyone who claimed to carry a 100 pound pack actually did we’d have thousands of hiker deaths every year in the US alone). But a survival situation is one time when you need to be cold-light-of-day honest about how much you can carry and what that load should be comprised of to give you the best possible chance of survival. As a general rule you shouldn’t carry more than 15 or 20% of your body weight, which for most people will be between 20 and 40 pounds. With this in mind you’ll want to take into consideration the weight of the pack itself (which must be deducted from the total load) and its volume so that you wind up with a bug out backpack that can carry the appropriate amount of supplies.
On another note, the only thing I had trouble with was #1. Yes, sleeping bags are big and fat and are a pain to carry, but they will make up for it in heat. You need that heat, at least here in the Pacific Northwest where I live. You use a space blanket or bivvy, you get either a miserable night (lucky), or hypothermia (normal). I wouldn’t mind packing a bivvy instead if I lived in a warmer climate, but seriously, don’t skimp on the sleeping bag.
Note: For long term reliable food supplies you should of course plan for a garden and growing your own. It is important to know that storage of seeds from many hybrids and other cultivated plant varieties sold in stores is not a good idea as their second generation seeds can't be repropaged in subsequent years. If they do produce viable seed, the resulting plants are usually inferior to the parent plant. Accordingly, we recomment purchasing open-pollinated, non-hybridized seeds or heirloom seeds for storage.

If you live in an area that experiences natural disasters that could result in an evacuation, it’s crucial to have a pre-packed bag with sufficient supplies for traveling. Convenient “grab ‘n’ go” survival kits have everything you need to stay safe, and well-fed while making your way to safety. Food, water purification tablets, personal blankets, and other necessities are provided in a duffle bag or backpack, so you don’t have to take the time to gather supplies before heading out. Typical kits contain enough food and water for 4 adults for 3 days.
