They want people who do Dungeons _and_ Dailies to Double-Dip. People who do Dungeons and Dailies get extra reward, because they put forth more effort (and they see more of the dev's hard work in the form of the dailies And dungeons). They want Dailies and Dungeons to both be viable, but you get bonuses for doing both. They _want_ you to Double-Dip by doing both. It is supposed to be a bonus.
Once you are fully 463 geared there is no reason to do dungeons if you don't do dailies. There is no 'bonus.' If you don't want to do dailies you do dungeons and then you graduate to raids. If you don't do dailies there's no point in doing dungeons. And the grind of dailies isn't to be confused with hard work. If we're going to have that conversation then LFR ought to just be removed outright.
Also the tone of your post basically implies that it's the intention of Blizzard for us to do the dailies and not skimp or ignore them - and I agree. In the past dailies have been more or less optional outside the needed enchants (in BC you needed the rep but you got that from the dungeons themselves). Now they are more or less required (unless you want to cap valor and just stare at it). Any statement made that these are optional feels like BS propaganda.
