GP was not talking about using Bitcoin for crime, but rather the (extremely common) crime of having your money stolen via fraud or whatever. In USD you have recourse there to be made whole. In btc, you do not.

You have no recourse when your cash is stolen unless you’re insured against that. You have some recourse when stuff from your bank account is stolen because you’re paying the insurance in bank fees and taxes.
Those are products you’re paying for. Similar products (and much more flexible/advanced) can be built for bitcoin.
That Bitcoin is used for shady stuff and is harder to track is a red herring for all 10 years of its existence. Come back when Bitcoin’s usage for said stuff is within order of magnitude of USD’s market share.
