> But then the food isn't guaranteed, is it?

You are correct but I feel perhaps missing the woods for the trees.

Every person's right tends to be someone else's obligation.

When obligations are met by state resources, there is then a responsibility to distribute fairly (because the resources come from everyone), this introduces hoops or conditions.

That doesn't mean that the right, or the obligation doesn't exist.

The need to ensure everyone gets food is absolutely part of the public understanding and discourse.

You can of course pick holes all day because yes, administering public welfare programs is hard.

Conditions where the state is obliged to do or provide something tend to be more complicated in practice than when the state is obliged NOT to do something (search and seizure, freedom of speech etc).
