I think you're saying exactly what I'm saying, but you might have said it better. I especially like:
If there's substance to {ordinals, inscriptions, runes} then it will find its market and be sustainable. If not, then it'll just fizzle out and drain liquidity from people who bought into it.
and
Until I see something coming from {ordinals, inscriptions, runes} that's not...then I'm not interested.
I guess my hope is that that something might just happen. And if not, that's okay too. I just don't see the silliness as being sustainable long term, think it'll fade eventually, and that something worthwhile may emerge.
