If ATC tells you to do something you have to do that (with rare exceptions). Doesn't matter if you want to go some other direction. So even if he wanted to go up the Anacostia, if ATC said go up the Potomac then you go up the Potomac so it doesn't have to do with not knowing where you're going, it's the ambiguity of the instruction. Could he have guessed that the Anacostia would have been a better decision since the mall is just up the Potomac? Sure, maybe, but the real answer is be rude on the radio if you have to and get that clarification.

> Doesn't matter if you want to go some other direction. I'm not talking about wanting to go some other direction. I'm talking about the previous departure clearance he received. Those are the "A very busy air traffic controller spit out departure instructions." followed by the "hectic voice said “we have an amendment to your departure are you ready to copy”". Those are telling him which way to go. And they don't just rattle them off and good luck. They wait for the pilot to read them back, and they check that the pilot reads them back correctly. I bet that he was not cleared for a visual departure out of DCA. So the departure he received must have had a list of nav points. Were they left or right? What restricted airspaces were there in the vicinity he should be aware of? You know, it is telling that those details are left out. Probably if they were spelled out it would be clearer how big a mistake the pilot did. Very conveniently they are mentioned but not described.

  > I bet that he was not cleared for a visual departure out of DCA. Why not? DCA has a charted, named visual arrival. A visual departure via pilotage is no different, and is very common for VFR flights. (Yes, they would've been given a departure clearance with a route to follow, but "follow the river" is a valid VFR clearance.)

That's on the chart. ATC doesn't need to (and usually won't) tell you about those. It's expected the pilot has done adequate preflight planning to be aware of them.

  You have to do a readback but unless you're familiar with DC geography you might not think to ask which river to follow. You could give the readback correctly and then realize you have follow up questions that can't be addressed conclusively by looking at a map. Correct move by that point was ask for clarification even if it made you sound dumb on the radio.
