The sections that are mentioned will most deal with strict KYC compliance, anti money laundering practices and due diligence as per the banking system. More or less these are the rules which are dragging crypto currencies into harsh regulations and indirectly they are called for regulated crypto ecosystem.
The classic story of only wanting the good parts of everything.
Cryptolovers want the government to accept crypto, they want the governments to invest in it, and they want to be allowed to spend it everywhere but god forbid they should pay sales tax or VAT or have to disclose like other assets their profits from it and get taxed upon it.
Exchanges are business, it's normal for a business dealing with any kind of financial transaction to follow the same rules as the other, funny again, people want protection like FDIC insurance to be protected against crappy exchanges but no way in hell I'm doing KYC or am I reporting this in my tax form or anything else.
You have to choose, nobody is doing anything against your freedom, and you can send and receive coins as you see fit, but once you're a licensed business you have to follow the same rules as everyone else, crypto or no crypto.
I understand it the other way around; what it means is that the exchange will not just report suspicious activity into the authority; by doing so, it will not just alert the authority of the activity but they will also be charged for allowing such fraudulent activity to pass through their exchange. But instead of them going to alert the authorities, they will take charge of the issue and handle it within the exchange. Exchanges do that slot unless something warrants the attention of the Fed, in which case they give control to the authority just over the suspected user account.
Exchanges are not law enforcement agencies nor have they judicial powers.
Exchange can't seize funds they can only freeze them and report them to a law enforcement agency in the country they reside in, they can't judge on themselves that those funds are clean and they are not, suspicious activity is reported and it's the authorities after an investigation that will decide if those are clean funds or involved in money laundering schemes.
To give an example, if in my shop you want to pay with a 500E euro bill and I think it's suspicious I don't have the right to put it in my pocket and then tell you to come in two weeks to as I find out if it's fake or not, I either report to the police and let them deal with it or I refuse it and tell you to go to another store.
