Yeah I don't think he's gonna just do it on a whim, nor will it be at Luffy's request. I think they're going to get into an EXTREMELY dire situation at some point closer to the end of the series. I'm sure you know that Gears 2 and 3 were already taking a toll on his body, and Gear 4 now even probably more so. He's been greatly decreasing his lifespan, so I also think it will be lame for Luffy to just walk away at the end of all this and live a regular life, like he won't be the most infamous pirate in the world.
