That’s their claim to argue against.
Of course in my opinion Madoff & MMM are fundamentally different than cryptocurrencies[2] because there isn't someone at the top who can hide what is happening or issue new coins. Arguably what is happening with Tether might be similar, but that's a very specific thing that you try to target with government intervention instead of blanket banning.

[2]: to be clear there are ponzi/madoff schemes in crypto, plenty actually, but if you weight by retail exposure to them they are not that common
The same lack of imagination is leading to most of these takes.
If I'm not mistaken, Bitcoin whitepaper was originally about easy P2P payments. Bitcoin has not full-filled this vision yet, but the cryptosphere as a whole is working on this (if you ignore the hype and speculation).
Visa/Mastercard, PayPal, banks can block or prohibit any kind of transactions if they wish so.
Look up stories of sex workers, OnlyFans creators etc about being banned from using these traditional payments systems.
Also look up fees that some banks charge for remittances - those range from 1.5 to 12% of the amount [1], depending where you're sending it. This does not include the cost of getting a bank account and a debit/credit card in those countries. Receiving a SWIFT transfer may be an issue if you don't have the necessary documents that explain why you have received the money.
PayPal actually does not even support most of the worlds countries. If you're writing a book you want to sell online, but Paypal doesn't support your country - you will NOT be able to get the money out of the publishing platform (gumroad [2], if you need an example). People are excluded from the creator economy.
Banks in developing countries use legal workarounds to get more fees from merchants using their systems or pay terminals. Merchants often have no choice but to raise prices, accept cash only or use some other kinds of P2P solutions.
And don't get me started on the absolutely insane inheritance taxes in some countries - the state is effectively robbing people (and their descendants) after their death.

There is a balance here too. When the wealthy can shop for tax and wealth havens until (almost) nothing is ever returned, they essentially rob the communities that supported and made them rich in the first place.
Governments should step in. If the only way to buy it is to commit to holding it for a while or to buy it in large blocks then maybe we wouldn’t get the kind of market we have today. One that is hurting lots of people.
