Has the issue of Sugar having years and years of use of her fruit continuously been adressed? Because when I read the point you made about using your DF without strain it gave me the ideea that Sugar didn't sleep at all for all these years...

It seems absurd to think that she would stay awake for so long just to keep this thing working... So then does it mean that fruit users can maintain characteristics of their powers even while asleep???

Does Luffy stop being rubber when he is asleep? Does he stop being rubber when he is unconscious? Because if things are to function like this, it would mean that Doflamingo's birdcage at this point is just like Luffy's elasticity and therefore creates absolutely no strain, it being just as natural as being itself. This might sound like speculation, but there must be scenes in which Luffy is sleeping and comically he still maintains his rubber properties.
