The most common reason governments say when they announce to ban or sanction anything in blockchain and cryptocurrency is "It is used for criminals".
See what banks are used for?
For criminals.
And how much some parent companies of banks had to pay for penalty?

Industry: financial services
Penalty Total since 2000: $388,802,802,308
Number of Records: 7,734
Note: The totals include only those entries matched to a parent company. The industry designation is the primary one for the parent's operations overall. The totals are adjusted to account for the fact that each parent's entries may include both agency records and settlement announcements for the same case; or else a penalty covering multiple locations may be listed in the individual records for each of the facilities. They are also adjusted to reflect cases in which federal and state or local agencies cooperated and issued separate announcements of the outcome. Duplicate or overlapping penalty amounts are marked with an asterisk in the individual records list below.
The total paid $ for penalty is $388.8B, it's not small.
The discussion can start with
Why governments don't ban banks even banks are used for criminals?
Why governments don't ban knife, gun, email producers/ companies because they are used for criminals?
They can Do crimes but they pay fines penalty and don't talk about this anymore.
In their daily lifes they wear suit and act nice they take dirty money they pay penalty just and criminals who give them will go jail yet they will just pay penalty.
But If nobody from the non crime circles don't know about it then it's all fine think about how many polite people you see daily in city they act nice and look like they are very honest but in reality they might be involved in bad things for them it's just business and nobody don't talk about this in their daily life they are just well known successful business people and probably nicest people who you ever meet in your life nothing about them wich show's they might be involved in bad things.
But every BIG criminal needs the small criminals because someone must do the low paid dirty crimes and money will be going into top of the food chain.
And Even If we don't feel direct harm one day the not legal guns sold on Dark Market Will harm just accidently those bankers friends or own people becouse some grazy person bought gun from the dark Market no matter how Nice someone is acting If the actions not Nice they harm society but they have karma one day for sure.
So that's how it is with them
