Binance.com stopping to give services to people from US does NOT mean US banned crypto! how do you even come up with that kind of conclusion?!
the only thing that it shows is that Binance.com does not want to or can not comply with US anti money laundering laws, it is possible that they are laundering money specially with all their tokens that they keep creating out of thin air without them being backed by anything (exactly what Bitfinex does with Tether).
it is also because they are creating a new platform for US citizens only

you gain financial freedom when you use a decentralized currency (ie. bitcoin) not a centralized website/service called Binance.
yes you're right, the reason why binance stopped supporting US citizens is that they can't comply with AML regulations there. without binance, crypto there will still be. so don't be too fixated on this.
it is difficult to ban crypto even with any regulation, because crypto is an anonymous decentralized currency. so even if one or two markets are banned in the US there will be new markets that will be released either from companies or individuals.
