đź“ť Original message:
Hello,
> This cat and mouse game can be won by bitcoin defenders. Why ? Because it is easier to detect these transactions and make them a standardization rule than to create new types of spam transactions.
One of the things discussed during the mempoolfullrbf discussion is that a small (~10%) of nodes willing to relay a class of transaction is enough for that class of transaction to consistently reach miners. That means you would need to get nearly the entire network to run updated relay policy to prevent inscriptions from trivially reaching miners and being included in blocks. Inscription users have shown that they are willing and able to send non-standard transactions to miners out of band (https://mempool.space/tx/0301e0480b374b32851a9462db29dc19fe830a7f7d7a88b81612b9d42099c0ae), so even if you managed to get enough of the network running the new rule to prevent propagation to miners, those users can just go out of band. Or, they can simply change the script that is used to embed an inscription in the transaction witness. For example, instead of 0 OP_IF…, maybe they do 0 OP_DUP OP_DROP OP_IF. When the anti-inscription people detect this, they have to update the rule and wait for 90%+ of the network to upgrade. When the pro-inscription people see this, they only have to convince other inscription enthusiasts and businesses to update.
The anti-inscription patch has to be run by many more participants (most of whom don’t care), while the pro-inscription update has to be run by a small number of people who care a lot. It’s a losing battle for the anti-inscription people.
If you want to prevent inscriptions, the best answer we know of today is economic: the cost of the blockspace needs to be more expensive than inscribers are willing to pay, either because its too expensive or because there’s no market demand for inscriptions. The former relies on Bitcoin becoming more useful to more people, the latter is the natural course of collectibles.

You cannot stop a soft-fork. What inscription creators did, is just non-enforced soft-fork.
