Sorry I'm not here to nitpick and while I think you fully understand the scenario, the only way the FAA can honestly answer that question is "A drone pilot is required to have a part 107 license to engage in the [commercial] business of capturing photos and videos and selling them (because when you do this, you don't qualify for the recreational exemption)."Is this pilot allowed to do this without having a 107 certificate/certification?
Sometimes I personally believe the FAA intentionally answers questions with non-specific answers (i.e. they don't address corner cases) and they try to generalize because they truly believe if they don't intend to enforce it (other than education or egregious) then it isn't necessary to get into the details. the best answer would be go fly your drone, take your pictures, and do whatever you want with them; just please get your part 107 to be on the safe side, ok?
