There is a difference between building something on top of bitcoin and finding an exploit to abuse the protocol.
it is part of the protocol. there is no exploit at this point. if there had been it would have been fixed by now.
Your statement also has nothing to do with the fact that the garbage being injected into the blockchain using the Ordinals Attack has zero utility.
i would prefer you to come up with a better word than "attack" to describe ordinals it's not an attack it is just a use case of bitcoin. i understand how someone may not like the particular use case but i don't think we have a right to tell people what bitcoin is or isn't. the market decides that. the people that are using bitcoin help decide its direction. and you don't agree with them using it in a certain way. and that's your problem. not theirs.
funny part is about larry and nutildahs delusions is that the junk is not part of the secure blockchain. the junk can be pruned off without destroying the txid that forms part of the merkle tree thats written into the blockheader..
then you've solved your own problem. just do that and you'll never have to complain about ordinals taking up space on the blockchain again!

meaning in the case of a chain re-org or an event where sybil nodes broadcast blocks with a different 'weight' element to a block. they can broadcast different junk attached to the same txid of historic blocks and not get rejected. without having to actually re-hash historic blocks..
there you go then. now all you have to do is make some blockchain reorganizations and you've gotten rid of casey for good. you've solved the problem so congratulations. end of ordinals. not only could you take down ordinals you could take down bitcoin too if you wanted but maybe that's for another day?
