“per federal law” is the sense that I refer to. Federal law includes stopping not only fraud, but political adversaries (ie. Canada), the aforementioned privacy preserving tools, trading activity between consenting parties in the name of investor protections, and various other violations of the force is only justified in response to force rule. It’s interesting how people that normally claim to support privacy will go all patriot act over financial privacy.

Regardless, I’m not sure why it’s relevant to bring up what you like about credit cards. You’re free to use whatever currency you want, we were discussing whether it should be illegal for me to do the same.

Non-reversible transactions are a feature not a bug.

If you want protection against that, get insurance.

Are you two agreeing implicitly, in that insurance IS the point of a credit card company?
