back to more serious things I think that aside from gathering curses during exorcism in his cult, geto also uses the properties he received from his sponsors as donations and turns them into shelters or any form of charity organization directed to nonsorcerer population because that way the negativity constantly circulating those places becomes curses or at the very least guide him to where the curses are gathered.
the use of a charity institution was a choice not from the kindness of his heart because he has no love for ordinary humans, it's a fiscal strategy so he can launder money for the expenses needed during his travels across the country in search of said curses for the upcoming parade.
