if ordinals had been baked into the protocol by satoshi himself and always had been a part of bitcoin then your argument would be pretty strong.
Ok, so let's say we ban this method of embedding arbitrary data in to the blockchain. Ordinals then move to embedding data in to public keys instead, which takes up more space and so the spam problem gets worse, rather than better. That would be fair game at that point because embedding data in to public keys has been possible since day 1 of the protocol?
ordinals wasnt baked in since satoshis day..
heck a bitcoin block wasnt even able to surpass 0.5mb until 2013 let alone 4mb of junk which was not even possible until 2017+
the ability to ad upto 4Gigabyte of junk is not something that was baked in as an ability to utilise even in 2023..
i date you or larry to even try and make a junk meme video of 4gigabyte and add it into the blockchain
you cant because rules that were baked in prevent it..
however over time the rules have been relaxed to by pass things
