Sure, but then you are still subject to the fees, restrictions and limitations of those third parties. And from what I've been told, the whole point of crypto is to get away from those third parties in the first place. That's my point.Exactly. Most consumers are using credit cards or PayPal or some third party to provide protection. And crypto works with those also.
Consumer safeguards have a cost. If you don't value those safeguards, then crypto is a great option for you. Same as cash. Zero friction, zero protection (though you can track crypto). But many people do value those safeguards, and view them as a benefit rather than a hindrance for any kind of legal transaction. I value being able to dispute a charge on my card and the bank being able to restore my funds.
Whether or not any transaction should be illegal (e.g. drugs, smuggling, etc.) is a separate discussion.
