Come to think that Bitcoin or crypto as a whole did become that popular just because it do totally oppose decentralization and if ever that becomes outlawed then it do really serves its purpose not unless or excluding into those projects or coins which are totally centralized then it would be that excluded. Do people do continue to make use of it? Of course it would be and because of decentralized aspect or benefit then we do have that freedom and since its mostly anonymous then there's no way that government could easily tracked it out.
You can't ban decentralization, that's the whole point of decentralization. What it will do is just push people to develop better solutions for accessing these things and having anonymity. It will have a negative impact on the market price for sure, but it will never be able to prevent people using it. Even with a blanket ban there would be millions of people who will continue to use it. As much as you can before it will cause what Abiky described 
If there were cases like he described, you would think about your skin, not freedom.
Highly developed humans think about things like freedom under any conditions, lowly developed humans think about the next meal at McDonalds. If there were cases like he described, you would think about your skin, not freedom. 
Plenty of people used Bitcoin when it was still illegal in their country, nothing is going to change about this.
