I definitely foresee preservation guilds forming as in @jasoncfinley visions. For example if 30's hand or DzChans dragon were to become unbeaconed I would very much be on board with looking to claim these amazing structures to preserve the areas looks.
It would also mean, for example in Dragons Watch, there are some extremely prime market stall spots close to the portals and I imagine quite a few people turning up there to try and compete to place their beacons on the spots if they timed out. I think it would add a good dimension to the game for intergalactic real-estate agents grabbing and selling on these prime spots of land.
Public auctions - how much am I bid for this lovely dragon ladies and gents!
