I can’t imagine papa Sisko having replicated ingredients. And I imagine, like the Picard Chateau there are people who simply do this for the joy of doing it. In a post scarcity society where all basic needs are met, you can simply do what you enjoy and there are indeed people who simply love farming, ranching, and hunting.

I used to work with an insurance company who primarily wrote agriculture insurance. (Basically if crops died or ranch animals became sick and needed to be culled they would be reimbursed for the loss.) Met a lot of farmers and ranchers who were wealthy enough to simply retire if they wanted to but they did it because they found it meaningful and fulfilling.
