There are different degrees of defending. Defending a boss and defending a boss's violent strike busting are two different things. Defending ordinals that have happened and defending ordinals being guaranteed in the future are the same kind of distinction. I defend ordinals, not a guarantee of them being able to exploit the bitcoin protocol forever. It's not black and white, and as libertarians we should remember that. Ordinals might be stupid since Bitcoin wasn't designed with large memory throughput, but they are voluntary interactions that don't harm anybody. Stopping them is fine too.
