This makes sense to a certain degree, but "just ignoring it" only goes so far: even seeing it is corrosive to a certain extent, and by the time you've even registered it enough to ignore it, a lot of the damage is done.
Perfectionists undergo a similar phenomenon, I'm told. After all, the modern "Do it badly" movement was itself a response to the corrosive effect of the "'Good enough' isn't" message permeating all of society. I'm not unsympathetic. In solving one problem, it didn't exactly create another -we've always had perfectionists to some extent- but it made that problem much, much worse than it had once been. But the fact is, it was done to solve a real problem in its own right, and that problem has not gone away.
What it comes down to is conflicting needs. The all-pervasive "'Good enough' isn't" came about because some people genuinely need it, and they genuinely need it at that level. The same is true of the now-pervasive "Do it badly": it is genuinely needed, and at this level. And you can't balance them, because they inherently undermine each other. So what do you do?
