People must understand that Bitcoin isn't anymore the plaything that it was years ago. Every exchange will face difficulties if they don't properly register their activities - especially when it comes to allowing people to exchange/trade crypto versus USD. If an exchange isn't willing to go through whatever is needed to be allowed to run a platform that involves USD, it will experience what BTC-E has gone through, what Bitfinex is, or will go through, Poloniex, etc. BTC-E however is reported to be involved in the MtGox theft back in the days. I don't like the government shutting exchanges down, but in case of BTC-E, if they are really one of the master mind behind the MtGox theft, may all involved entities burn in hell.
You are absolutely right mate, Most of the person in this industry they don't know the deepest meaning of bitcoin. Those exchange too must realize how to do proper requirements to make their activities be well organize,. That's why there is a big possibility that bitcoin can be a threat to dollars because of its criteria it has which is bitcoin.
