Like I alluded to, there are alternate definitions to most scientific concepts/labels. I have never read that to qualify as DC, we have to invent some device which converts that electricity to mechanical work. But that doesn't mean such a definition doesn't exist. But it is odd to criticize someone for holding a belief which matches the most common definition of a scientific concept.
As an aside, from a thermodynamics perspective, electric current of any type is a form of work. Work is any energy transfer mode which occurs without entropy transfer. There is no entropy transfer with electric current, so odd as it may sound, a thermodynamicist would say that static electricity is a form of "real work."
