If Harper is truly waiting for LAD/CHC to move pieces and offer him better contracts then he's taking a huge risk. There's probably a decent chance that Machado signs with us soon, as in before the holidays, leaving Harper stuck with the Phillies who then get all the negotiating leverage in the world.
In other words, while Harper is holding out to make sure he gets the most money, he may simultaneously be screwing himself over by ridding himself of his top suitor (in terms of money)
