I get the point you're trying to make but.. still I don't believe you can compare a video-game for I pay to play with things like having a job or paying for gas or going to hospital.
They are different things in a different reality.... a game is just a game.

I don't think that Blizzard implemented the daily-system as being compelling gameplay.. they just added it to make the content last longer.
They know that there are players who will do them, how mindless and boring they might be.
