Which is your opinion. People who use ordinals are of the opinion it is not spam. I happen to agree with you - ordinals are completely worthless spam - but I don't for a second believe that my opinion is the objective truth and everyone should do what I say.
If your barometer for what is spam is anything which isn't in keeping with "a peer-to-peer electronic cash system", then we also need to ban all transactions from centralized exchanges, since they are not peer to peer either.
If you don't believe your opinion is better than other opinions without anyone convincing you that other opinion is better yet, than you have no opinion at all.
I think the point been discussed is about "purpose". The purpose that brings passion to Bitcoin is having a "coin", means of exchange, store of value, that is independent from state and gives people sovereignty on their own money.
Seeing the blockchain created for this purpose been used as a cloud-driver to store images and non-monetary tokens or data in general is very painful.
The question is, if ordinals and inscriptions in general are bringing harm to bitcoin in any way, preventing its usage as money, isn't this something worth doing something about? Block space is been flooded with images (memes, useless), and jsons creating tickers that represent nothing in reality. This is Ethereum business, not bitcoin.
I don't mean a hard-fork, or a soft fork, I really don't know, but I think it worth discussing without throwing out that anything related with discussing this would be "censorship".
They already pay for the space they use just like everyone else. And at the current fee rates, that is very expensive indeed.
Yes, they pay for it, as I pay for Google Drive space or iCloud... they are using my node as a cloud storage and paying for someone that's not me. It's expensive and unfair with "amateur" node runners, with their 1 TB storage and a raspberry pi.
At some point this might push these small node runners out of the network and make Bitcoin less decentralized.
So as I've pointed out above, you can transfer UTXOs from one address to the other and embed arbitrary data in the public key (or even in the signature). It's impossible to ban that without hard forking to introduce some new zero knowledge proof that someone knows the private key of any address before coins are sent to it.
Before Taproot we didn't have anyone trying to play Ethereum on Bitcoin, because it didn't worth the effort. After Taproot, what can be done to make annoying, difficult or unprofitable to save images of dogs in the blockchain?
