My thought was concert tickets. An artist could set an absolute maximum for how much a ticket could be resold for, and the energy costs of maintaining the blockchain would be time-limited to after a show or tour completed.
Of course, Ticketmaster would never allow that because it effectively nukes the scalper market, which they also run through stubhub.
For everyone arguing it’s a niche issue, there’s plenty of non-LGBTQIA people who also care about trans rights. And the fascists are going to keep flogging the issue so the only way to deal with it is to address it head on. The fact that this is a question about Newsom makes this a problem.
