Most/all of those methods have (often much) greater friction than cryptocurrency. I'd guess that, if cryptocurrency were banned domestically, the payouts would significantly decrease, and probably reduce the frequency of these attacks.
But, even then, such a ban would probably have a negative effect on cybersecurity progress, since these incidents are motivating fundamental changes to cybersecurity awareness, policies, procedures, and technology.
