it lets you spawn PWPs from 100 bell coins
however i (personally) dont know if it works without the permit.
since you dont have to talk to isabelle to place them, though, i dont see why it wouldn't work?
I guess I'll use that, I just wish there was a way to skip the dumb thing. If there is something I hate about acnl it's that permit.
