The sale of new Birkin bags is famously invite-only. In that context, to "sell" to "everyone" means making the bag available for sale to everyone. "Anyone" would have been a less ambiguous word choice, but it's a minor grammatical issue and the meaning is still clear.

I didn't read anything about the everyperson beung able to do this.

There was an implied ‘who is on the waiting list for a Birkin bag currently’ in ‘everyone’. They did not mean every single person on Earth, they meant Hermes could sell a Birkin bag to every interested buyer.
