When it comes to the form of property, I agree that the government is more cautious.
After all, Bitcoin has not been around for a long time, and it is technically difficult for the government to grasp.
This is the beauty of Bitcoin. I agree with this.

Perhaps the ban is due to political factors.
A bit of a conspiracy theory indeed. The following are purely assumptions.
I don't quite believe that if the US government wants to control the Bitcoin community, there is nothing they can do.
It would be scary if, I mean, if the Chinese use of bitcoin is very common, maybe our competitors will control the bitcoin community.
Just like they were going to pass a bill in Congress that would take away the US bonds we bought.
They can get anything they want.
They might say that there are Americans in the Bitcoin community and that 10% of American technology must comply with the Export Act.
They might say that Bitcoin is suspected of money laundering and that community leaders have to come out for a hearing and add a piece of code to operate legally in the United States.
The reasons don't matter, the result is "they can get anything they want".

To be clear though, the Bitcoin community right now is very nice and not distracted by a lot of ideology.
