I can't foresee a situation where I personally would, but I can see doing it if living elsewhere with a new citizenship and no intention of ever getting social security or any other sort of US benefit. I have a friend who lives in England now and is likely to eventually relocate to his wife's home country, never returning here. If he didn't have some ties he does to the US (he owns land and is a tribe member) I don't see why he wouldn't consider it.
The pews never miss a sermon but that doesn't get them one step closer to Heaven.
But at least the pews never attend yoga!
