Good points.
In ordinals/inscriptions case I believe the data is in the witness, so it lives in the transaction ID, but not in the UTXOs….. so it’s not really “on the blockchain” in bitcoins case. See Guy Swan’s latest on this.
We will see if these things will hold their value overtime. I’m betting no. Might take a few more years for this to play out.
Thanks for the thoughtful exchange.
