You get about 600 dukes for a buried supply quest. This is usually done less than 10 minutes and does not require much effort. This quest gives you food and as a reward XP, Dukes and items that you can sell for more dukes. With the dukes you can buy food that doesn't give you food poisoning. Accordingly, the player learns that it is not necessary to create a garden at all.
For other quests you get more dukes, more XP and better items. Many players do quests all the time anyway and sell everything that they don't need. So it's no extra effort to get enough dukes to afford the food for the day.
Some of the users in the forum have already written here that they do exactly what I suspected they would do. They simply buy the food from the vending machines because it is the most convenient for them.
I've read postings before that players don't have a garden anymore because they find more than enough food. Even in A17 where canned food gave you food poisoning. Since canned food no longer gives you food poisoning, they have no reason for farming at all.
I will certainly create a garden because I like it but for survival it is not necessary and there is no incentive to do it. Therefore I assume that many will no longer have a garden even if they had one in the past.
There are now more than enough sources for brass in the game. Wrench every air conditioner, every car and every heater you find and you'll never have a lack of brass. If you're lucky and find the right book you can even get brass if you destroy a door or wrench kitchen sinks.
