100% voter turnout assumes that not voting is a not an meaningful expression of someone's right to vote. Unless there's option to express this within the voting system, there will always be voters that don't vote. Second, if it's safe enough to bank and file taxes online, it safe enough to at least take an unofficial, but publicly published count online; people could for example update their vote during the run up to the official election. Some countries have had penalties for not voting. Unclear if this helps, or hurts, the system.
