This event is not about commerce. It's one thing to sell an NFL or concert or music festival ticket for profit. Those things are all about profit, and I don't see any reason why a ticket-holder shouldn't get in on that revenue-stream.
But this is essentially a non-profit event, that is an experiment in alternatives to commerce. If tickets become so expensive that only the wealthy can afford them, it sabotages the experiment.
Please help us preserve the nature of this event.
