For simplicity, play until there are no more legal moves and then count each side's stones on the board.
This tacks on a lot of trite moves at the end of the game, which nobody sincerely wants. Half of the game could be what happens after yose!

yeah, I'd start from here, and even go as far to say, why stop? just keep playing (and capturing), until the one with the most stones on the board wins.
but soon, you'll realize that most of the moves will be pointless and not actually affect the final outcome of the game.
so you might naturally decide to agree to stop the game at the point where the outcome is no longer being affected, and just count everything from there -- stones on the board, plus empty territory. That is, in fact the idea of the game -- the one who controls the most area of the board, wins.
but then you might take that to the next logical shortcut, and save yourselves some time by counting only the empty territory minus the captures. Afterall, its algebraically the same thing. But this shortcut introduces some potential problems, that the previous method didn't have, namely: 1) having to keep track of prisoners, 2) playing in ones own area can adversely affect one's own score. So as long as both side can agree on the status of dead stones, this final method seems simplest.

Perhaps. But of course the question becomes, what if they can't agree?
Well, then, you keep on playing.

What xed_over is talking about is equivalence scoring, so if the point at which you stop play and agree on dead stones comes after a Black play, White gives up a stone as a prisoner, so that the number of stones on the board during counting is the same for each side. And don't forget the group tax!
