there is a limit of how many people you can be physically present to coerce up to end of election, making it inviable en mass, thus impractical.

		Social pressure can make it scale pretty well. For example, there could be a neighborhood election day party. You vote when you enter, the organizers observe how you vote, and then you leave your devices in a storage locker. The party continues until voting has ended and the results have been announced.

how would one know? they're they know a transaction happened, but they do not see the contents of a transaction
