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?

Here in Australia you don’t even need a ticket to get in to the terminals and security never checks your id, you just walk through the scanner and have your bag scanned. They only check your boarding pass at the gate before your flight. Never once had my I’d or passport checked. You could just walk in with anyone’s ticket and no one would ever know or check.
