If you start from an assumption that there should be no regulation, then your conclusion will be that there should be no regulation.
That's not actually an argument for anyone who doesn't share your assumptions though and is largely just lazy thinking.
Cash also has physical limitations that make large cross-border transactions hard, which crypto does not.
Start from the assumption of liberty and the freedom of association. Unfortunately, most people don't believe in human liberty and prefer varying degrees of slavery.
