I agree with your take on the BTC Ordinals... I'm think that they might be just a flash in the pan. I hadn't really thought about the knock-on effect for Lightening. I've only used that in passing.

But I'm still not really sure about the ongoing royalties for the original artist. I'm pretty sure that you are aware of the debate about this on the Ethereum side of things. They aren't enforceable at the smart contract level as things stand at the moment... and although there was much made of this to lure in artists (and I would dearly love it to be true...), I don't think it is a thing (at the moment...).

Even as an artist (albeit as a musician...), I'm still not convinced that the NFT thing is everything that it has been promised to be.
