The reasons governments ban or restrict cryptocurrencies like Bitcoin are complex. As you noted, each government has a reason. However, lets analyze. Comparing Bitcoin crimes to crimes with other assets is like comparing digital and real footprints - the medium changes, but the intent doesnt.
Bitcoin's volatility is real, but so are traditional stock markets. Remember 2008? Banning a volatile asset is like blocking the sun with a sieve.
The decentralization of Bitcoin is game-changing. The central banks' inability to regulate it worries them. Yes, some criminals use Bitcoin, but to call the entire ecosystem "bad" because of a few bad apples? What a reach. If we dig deep, the main difficulties seem to be lack of comprehension and fear of losing financial control. Thus, bans.
Based on the explanation I got from this forum users concerning volatility, volatility is even good for some businesses in the sense that if you invest some money in Bitcoin and the price suddenly spikes, you can make an instant profit. Just like I am accepting Bitcoin payments in my business and the current Bitcoin price is still low, let's say I have accepted up to 0.09 BTC with this current rate of Bitcoin price, and luckily the Bitcoin price has risen to $35k, which means I will even have an additional profit for my business. The problem is just that some people didn't really understand Bitcoin very well before they decided to use it.
Well, I know that with time, some of those countries where Bitcoin is restricted will lift their bans and restrictions.
