If everyone on Hive did actually vote on the return proposal, than yeah, sure. In that hypothetical case, the best we could possibly do would be give a proposal the exact same vote as the return proposal. I'm not sure how the system would react to a tie... would a proposal tied with the return proposal pass or fail? Hmmm 🤔
But it's a moot point, since all of Hive is very very unlikely to vote on the return proposal. Blocktrades, for one, with his enormous vote, will likely never vote on it. So I think we are safe from that situation.
