you cannot stop spam pubkeys…and those show up in the utxo and cannot be pruned you are incentivizing centralization as ram requirements push minimal hardware setups off the network. The purpose of the op_return is to prevent utxo bloat.

Do you see it now? The ram requirements are already making node hardware options more expensive.
