"let" is a big word specially when you are talking about a decentralized network. it is like asking will they "let" the torrent network, the Tor network, .... and other peer to peer networks survive!
First of all, torrent is not used to make transactions or circulate values.
You must not forget the situations with kat.cr (kat.ph).
you see, when it comes to decentralization, nobody has a say in what the peers on that network should or shouldn't do. of course fighting crimes and illegal activities is a must, and by preventing things like bitcoin you don't fight crimes you just made yourself look like a fool.
Nothing's decentralized anymore as everything is coming under regulations or straight bans. If you will use, why are you into Bitcoins? Ask yourself.
You are buying or selling it just because you are interested in exchanging values and making profits (growing your capital). But, once you convert your Bitcoins to fiat, you convert your decentralized world to centralized, don't you?
hmmmm.... this had me thinking. since the internet can't be shut down as that would result in pandemonium, then in the event that they decide to declare a ban, could they do what they did to torrent sites on crypto? the government was able to pull the plug on torrent sites like tpb or kat.cr but would the same be possible with digital assets? i'm still positive that whether the government likes it or not, digital assets will still survive and thrive. i think that it's not something that the government can control...
