Lost recap: postscript

I guess there's another possibility: divinity working within physics. Everyone who Jacob touched is outside the norm physics-wise. They come back, safe and sound, memories intact, but everything DID change. Just not for them. They're like their own little bubbles/islands. The plane never crashed...for everyone else. The reset happens for everyone but the main, living cast--and this includes Ben because he got touched at the last second before Jacob "died."
