But it's an open system and a permissionless ledger, WHO ARE WE to say what/how it's actually intended to be used? Because if for you, there's truly a "how it should be used", then it's probably better to use a centralized, permissioned system to use exclusively for payments, no?
What can we actually do if the transactions that "are not supposed to happen" are happening in a censorship-resistant ledger? Do you propose censorship?
Bitcoin Whitepaper says this:
A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Bitcoin isn't as permissionless as you say because Bitcoin has some anti-spam filters, you can't get transaction below 1 sat/vByte confirmed while in the past you could.
Ordinals spam the network, drive up the fees high and make it impossible for the rest of the people to use Bitcoin for what it was meant to be used, for payments. Non-financial use cases distracts Bitcoin from its monetary goals. Freedom doesn't mean the ability of doing anything.
Do you want freedom in the world? Imagine that there is a total freedom. What do you think, shouldn't we be punished if someone kills someone? A freedom doesn't mean you have every right to do in this world. There are still limits in freedom and will always be and should be!
