Previous sentence:

> If you bought the ticket off the event’s official ticketing agency (not a sketchy reseller)

> The risk with printable tickets is that a seller could sell it to multiple people, who all print it out, but then only the first person who uses it can get in?

Note that the portion of that you're quoting that you didn't quote is "If you bought the ticket off the event’s official ticketing agency (not a sketchy reseller)"

I.e., we're specifically talking about someone holding a ticket that they purchased from Ticketmaster. If there are multiple copies floating about, presumably at some point the artist (/the actual event) is going to be unhappy that Ticketmaster is screwing their fans/attendees over.

Ticketmaster has a system for transferring tickets, if you want to buy or sell tickets.

There could very well be a reason for someone to only sell a physical ticket, or not transfer it through ticketmaster, but I have yet to find anyone but scammers that want to do that.

The reason is, just as you mention, that scammers will try to sell multiple tickets. Then one (or many) sucker turns up to the avenue, only to discover that the ticket has already been validated.

>is that a seller could sell it to multiple people, who all print it out

They can't "print it out" because it's a rotating code.
