A decentralized system makes it unique. And some people like that, except for some governments in some countries that have banned all bitcoin activities. They feel threatened because they cannot monitor their activities, and they assume that the world economy will be dangerous.
Set up in the sense of banning or regulating a blockchain network? If it regulates a blockchain network then it will not be able to, but banning the activity is very possible. Just look at China, their government prohibits all crypto-related activities.
