That's an understandable reason to not like the argument, and I'll tell you that as someone usually on the other side of the argument I don't like how those who think games should be entertainment seem to think that games that have a story are automatically somehow worse in gameplay. Like developers only have so much brain power and if they take any time thinking of a story the gameplay won't be as good, but I have played many games that show that great story and great gameplay can and do coexist, so why not have both?
As far as the original topic, I would tell you that you can't always assume people making the games can be and should be classified as art argument also think that games purely for fun shouldn't exist. I certainly don't think that just like I don't think popcorn summer flicks should disappear.
