If I had official retailers refusing to play by my rules I'd be telling them I'll be looking for alternative retailers who would. Such a threat would normally be enough to slap a professional business back into line, and good riddance if they won't play by the rules; they wouldn't be the sort of people I'd want to do business with.
I think it works in the other way. It is not in interest of the Foundation to police it with current pricing terms. It even goes against educational principle if enforced really strictly. As jamesh said

Retailers would be foolish in the extreme to sell bulk at $5 and $10. I would be very surprised if any did it for any length of time.
This somehow confirms my previous conclusion that the $5 price make it a zero profit or even practical loss for retailers when counting also handling of returns etc. So the one per customer rule is there not for Foundation but for retailers so they are not obliged to sell you second one at that price if they don't want.
So if e.g. Pimoroni allows one per order they either don't care as policing the one per customer rule would cost them more or they bear the loss and make it somewhere else due to additional sales related to happy Zero customers. Or they are simply cool pirates who don't like enforcing rule that does not make sense.
Initially I thought the $5 price can be real but considering that even Chinese manufacturers/sellers cannot match this price on similar hardware now after 2 years with all their minimal profits, low labor and shipping prices, no support, no certification, low quality etc ... it tells something. And I guess all parts of the chain possibly agreed to this idea of sacrificing their normal profits for reaching this $5 goal starting with major part manufacturers and ending with retailers. So that's why it does not scale and once you want to sell it in bulk with normal business terms between all involved parties the price doubles even for high quantities.
