I suggest starting one as an experiment. You control it. See how long you can restrain yourself from wanting to delete something.

I make things that people want, they pay me and I use the money to buy the food from people who are selling it.

The thing nobody is willing to admit is if free food and shelter for everyone becomes a thing, the population would explode. Every system in nature needs a balance. Any organism, animal, living thing, humans included, will increase in population until the limit of resources is hit. We have no natural predators so our population is limited solely by the resources we have access to. Feeding everyone would actually increase the problem of trying to feed everyone.
