It's a bit pointless to argue something without agreeing on the terminology first. Light is a particularly nasty subject with lots of seemingly similar but crucially different quantities.

I think you guys simply disagree on the terminology. Obviously the larger surface area emits more "photons per second", but it doesn't emit more "photons per square meter of material per second" or more "watts per square meter of material".
