“but Leket, Peah, Shich’chah, and Maaser Oni — to remind prospective converts that the world belongs to HaShem, not to us.”
None of these 4 gifts go through the hands of any bureaucrat.
It is an interesting question why prospective converts are informed about these Mitzvot when they do not get a portion in the land to farm.
Perhaps it is to assure them that they will not starve if they convert?
The “talk” given to would be converts contains warnings of negative consequences, but also also positive consequences.
This belongs on another thread…
