It’s not a misunderstanding. The government is restricting it because they understand it. While I like to think that they ban and restrict it so they can be in control, I also see that there are worries about cases where people use Bitcoin wrongly (to even pay for illegal things) and due to anonymity, you cannot trace it. Also, the government likes tax, they know that Bitcoin not being able to be traced wouldn’t let them take their cut of one’s money. Over time, more government will come to terms with Bitcoin, you can tell if you compare the present to the past.
A bit of the government do understand bitcoin and a bit of the government don't understand bitcoin, I think that you've almost covered all of the possible reasons on why they ban it because they understand bitcoin so I'd like to take on the reason why they ban it because they don't understand, it's just my opinion so feel free to correct me or something, just don't hurt my feelings.
For me, the reason why I think that the government bans bitcoin because they don't understand it has got to do with xenophobia or the fear of the unknown, they don't know how the technology fully works and how they can utilize it to the means that would serve their interests be it selfish or altruistic, also the fact that the government have a hard time approving new technology means that they're going to do the same with bitcoin here, it's going to be full of red tape and bureaucracy. Hopefully, I'm just being delusional about these assumptions that I've talked and that bitcoin is doing just fine when it comes to it's relation with a lot of government, they'll eventually give in though, look at what's happening to Argentina with a pro bitcoin president.
That is correct, because before there were other countries that banned Bitcoin, and then later the ban on Bitcoin was also lifted. The question is, why did they withdraw? and they suddenly adapted bitcoin to their country. It's clear that they didn't understand Bitcoin when they first heard about it.
Because maybe when they first encountered it and heard it, what they thought was that they couldn't control it and had no benefit from it, or maybe they also thought that it was a threat to their country, but the truth is that later they realized that it would actually help.
