I think there are fundamentally 2 good technical take-aways.

1. Bitcoin lacks fungibility. 1 sat != 1 sat. There is surveillance and taint and now this.

2. Bitcoin is the most permanent monument upon which to write things, even if it's meant for transactions; it is obviously desirable to put other fancy things on there, like contracts, titles, nfts, etc. if you want to truly depend upon them for real life reasons.

I believe both of these issues are addressed by Roll-ups tech, and I'm hopeful that this Ordinals stuff will push people to accept some soft-forked changes to Bitcoin to enable such a thing.
