If I let a paper dollar bill fly into the air so I can take a picture of it with the clouds as a background, money is transferred from me and will most likely be received by another entity too. But my goal was never to send it to a receipient. Rather it was a legacy act and my sole intention was to take the picture. I couldn't care less if anyone actually received my dollar.
Ordinals/runes/BRCs pay a fee, but their outputs aren't having any intended recipient. Rather it's the act of spending, not spending AND receiving which is considered more Alice sends to Bob type of a transaction.
I'm wondering. What if a miner accepted a rune TX without any fee? Would we see a transaction with literally 0 BTC spend. No feed no nothing? I'm wondering if this is feasible at least in theory.
I can see some point into to calling this a non financial transaction actually. It's not as harmful to BTC to classify TXs based on their intention and I see it as a different act as promoting enforcement action against coins.
Again, it is not that I don't understand your point of view. I absolutely do and it is not really about disagreement here.
But Bitcoin, the whole way it works and how it is set up with skin in the game, with incentives for miners to act in the best interest of the network, makes that classification kind of unfeasible. I admit it is probably more philosophical, but I understand why someone would be against that classification. Because the Bitcoin network won't facilitate runes TXs without fees. It may do so, but not in general. This is why the classification is problematic. The network does what is best for the network and best for the network is when their are finances involved in any and all transactions.
You could go with this classification for the purpose of building some kind of overview, but that is why I said it is misleading and that is what PrivacyG was referring to, correct me if I am wrong. The network won't get clogged with 'non-financial' transactions because first and foremost every miner is primarily interested in the financial incentive, not in the message anyone wants to inscribe or get out there.
As I said we don't really disagree, no argument here. But there was a detail in the semantics that may mislead the average user with regard to their perception of what the Bitcoin network really does and why it tirelessly and flawlessly continues to operate. Skin in the game, it is all about the financial transaction and nothing else. The network has a variety of tools to neutralize miners including zero fee rune TXs. And you know that all those tools attack where it is most painful, and it is all about the financial level, not the non-financial level because it essentially doesn't exist.
If the 'non-financial' really were 'non-financial' transactions in the truest sense, the miners including those 'non-financial' transactions wouldn't last for long. They would be outcompeted as other miners would accept high-fee paying TXs and leave the junk on the table. They would have block propagation disadvantages, could suffer from fee-rate filtering and anti-spam relay policies. A couple of other things are possible and they all boil down to one thing and that is financial incentive.

You and I know what is being said here, but with the Bitcoin protocol in mind, it looks a bit like a misrepresentation. This would be even more true in times when the network is clogged and transactions cost a fortune.
