Maybe, governments are on the offensive against privacy coins like Monero. I believe Australia outlawed it. I wouldn't be surprised if increasingly harsh penalties were imposed as their popularity grows
I was just reading today the IRS has an outstanding bounty of 625,000 for anyone that can find a privacy vulnerability in Monero, not that anyone is gonna sell it to the US Government for that little when you can get so much more on the dark net/black market
The thing about decentralized things though... they tend to be nigh impossible to effectively ban.
