That's like saying that because a comic book comes out every month, as a distinct and atomic structure (at the level of the comic-book abstraction), therefore that proves that continuous time is not a necessary part of reality. I suppose if you're only confining your context to the serialization of a comic book, then sure. But that hasn't proven anything about quantum processes occurring at ~10^8 times smaller length and time scales.

I’m sorry if you don’t think a bounded entropy field becoming a quantized object of time through proof-of-work tells us anything important about reality. You cannot subdivide the temporal state transition the data represents. If you’re comfortable continuing to double-spend your beliefs, that’s your choice. You don’t get to believe in both centralized quantum computing and Bitcoin. They rest on incompatible definitions about time, finality, and computation. Eventually, time will force a reconciliation and you don’t get to pick both sides.
