Indeed. Bitcoin is neutral towards monetary transactions. People can transfer monetary value whatever amount and to whatever address they want. Bitcoin is also neutral towards people. Bitcoin never refuses and account to anyone. That is why Bitcoin is for everyone. But Bitcoin is Monetary network and not a spam dump for shitcoiners and scammers. And it needs to be protected from those, just like it needs to be protectd from DDOS - billion transactions with 0 fee for example. In that regard, the fees are a filter as well and they are on Core too and have been forever.
