domestic flight never matches your flight ticket with your idenfication, how do they know it’s the right person boarding the plane?

Question

Just theoretical question but for domestic flight within the US, when you enter the gate for security check, you just need to show your ID/ driver license. When you are boarding the plane, they just need to scan your ticket either in paper form or on the phone. They never match the name on your flight ticket with your identification, does that mean, if you buy a non-refundable ticket and you could not make it, you can easily transfer or sell your ticket to someone of interest to travel to the destination?

You would have to find this person in the secure side of the airport, which is just not going to happen because everyone there also has a ticket.
