Something need not be practical to work in politics. (Obama comes to mind.) The political damage caused by being excluded from the ballot just because he won't provide a simple document is too big a question mark for people to give him a pass on it a second time around. If he concedes a state because he won't give a copy of his original birth certificate, he's toast politically. This political reality will be reflected in the electoral college later.
I guess you didn't understand. Being excluded is meaningless because he wasn't legally on any ballots in 2008 and he won't be on any ballots in 2012. We vote for electors because that's how all the States choose electors. Such electors do not even have to be chosen by vote. A State could choose to have its governor appoint the electors or even choose them by lot. The chosen electors are the ones who vote for President. Read the Constitution.
