I answered that in my comment above, but it was an edit so you probably didn't see it in time.
Expanding on that answer, I think you're making a case for DRM here. Mario wasn't supposed to be not-blurry so we shouldn't be allowed to see him like that. If that's your opinion, I disagree, but fair enough. It's an entirely different thing though to assert that modern artists should not be making new pixel/block art, because it seems to me that their intent has value, too.
So the question becomes whether you object to that art style, or just the commonly used name for that style. Personally, I think you're going to have a hard time with either one, especially given the fact that the common usage of the word "pixel" has always been blurry, and that you could simply avoid modern "pixel" games at no personal cost and still allow other people to make and enjoy them.
To me, that doesn't seem so much in support for DRM, so much as support for something like the negation of "death of the author".
I think there is room to say both "this was the authorial/creatorial intent behind Mario's sprite, which should be acknowledged as being distinguished by being the intent" and to say "I aesthetically appreciate this deviation from the creator's intent, more so than the original intent."
The deviation in interpretation from the original intent is, I think, a new (derivative) creation, in a sense. (Though it may be an accident, and might not have an intent to create behind it.)
But we should appreciate modern pixel artwork as a cool retro-themed anachronism, not an actual representation of what displays rendered in the past. The idea that a pixel is only a 2D square gets in the way of that -- ideally, people could understand that it refers to both a point sample as well as a box-filtered rendering of that sample, and those two senses imply different ways to view a set of pixels.
