An argument could be made that the ability to move money shouldn't be restricted to the "law abiding".
Governments not only have the power to restrict the movement of money but tax records and transaction details let them know 90% of the most important details about everyone.
Additionally, sure without crypto there wouldn't wouldn't be these kinds of ransoms but the same attack could be used for terrorism/warfare. These ransoms just provide the incentive to develop solutions. A terrorist attack that had no option to decrypt the data could completely shut down entire countries.
