I'll continue not promoting money laundering and advocating for protocol level fungibility
Protocol-level fungibility can be used to launder money so by your own logic you're promoting money laundering.
not fungibility that depends on a 3rd party breaking the law and users being participants in that choice to break the law by using said third party.
Fungibility on its own is not against the law, at least not where I am, and if it ever is outlawed then it would likely make protocol-level fungibility (or usage thereof) unlawful as well. For example some exchanges delisted Monero etc for "compliance reasons", which is a good indication of how this would play out.
