Removing OP_RETURN limits will ultimately not change anything because garbage data is already being inscribed in blocks at a lower cost as input data. It does however set the precedent that node runners should not be able to configure these things and that the blockchain is for any kind of data, not just financial transactions.

Does that make Bitcoin a better money? No.

- It makes people using bitcoin as money have to compete with people abusing bitcoin with shitcoinery for block space and increase fees.

- It bloats the UTXO set making nodes more expensive to run, ruining decentralisation, the thing that makes bitcoin not a shitcoin.

Adding an anti-inscription filter will make it harder (not impossible) to attack bitcoin in this way and sets a precedent that the blockchain is strictly for financial data. This aligns with the intention of the protocol as stated in the title of the white paper "Bitcoin: A Peer-to-Peer Electronic Cash System"

Does that make Bitcoin a better money? Yes.

- It makes it harder for people to use bitcoin as something other than money, keeping the block space almost entirely for financial transactions.

- It will prevent further bloating of the UTXO set, giving improvements in storage some time to catch up and ensure nodes remain (relatively) cheap to run.
