If they don’t know how to/aren’t currently gardening, they are going to be very disappointed and hungry.
This should be posted on every one of these threads. The seeds are the easy part of gardening and that assumes that seeds are selected for the growing zone you live in. I have looked at the advertisements and researched a few of these companies and noted lots of problems. First and foremost, seeds gathered in the south may not grow well in Northern states and vice versa.
Gardening takes practice, soil preparation, irrigation, protection (pests/blight), fertilization, knowledge of plants (can’t plant some near each other), pollination, and the list continues. Even assuming a novice was able to grow a crop there is an equally daunting list of items/skills required to preserve the harvest if you plan on eating it year round.
Anyone thinking they are going to bug out to live off the land with a pack of “survival seeds” on their back and some rudimentary hunting skills like some kind of “Prambo” (prepping Rambo) are setting themselves up for failure.
If you are reading this and live in a suburb and plan to head for the hills you should be practicing now in your backyard to understand what you really face. I would concentrate on learning to grow staple crops (like potatoes) to get started and practice storing them as well. If you are not currently gardening and learning about gardening don’t count on it as part of your preparation!
I’ve seen multiple history documentaries on the people sent to live in the Western United States and settling in Australia. We’ll solve the urban poor problem by sending them to the unsettled country to farm! People who had no idea how to farm were sent out to the wilderness. Those few who were farmers pushed out to the unexplored areas were able to make it, because they knew how to farm and only had to deal with rough territory. The city dwellers who had no idea what to do typically drifted back to the cities or became miners.
