how would people buy cryptocurrencies and trade then if there is no fiat. they deposit fiat, buy bitcoin or some of the altcoins in a dip, sell on top, withdraw fiat profit.
also there isn't much wrong with regulation if it is done right. we can see the good example of it in Japan. their Forex exchanges are now adding bitcoin to their platform and they are all regulated and working without any issues.
OP, is simply saying people should avoid KYC/AML regulations usually linked to Fiat companies and trade between Alt coins. So you would buy Bitcoins through Localbitcoin or even regulated exchanges and then transfer the coins to these unregulated exchanges to be traded. < No Fiat withdrawal will be provided >
The unregulated exchanges will be very risky, because no oversight will be done and it would attract a lot of scammers and criminals that would launder money there. ^grrrrrrrr^

It is possible, I did it. I bought BTC at bitcoin.de, then I opened at Poloniex first, and Bitfinex second, transferring some coins on each account. Then I started trading altcoins.

Well, there would be no money laundering on altcoins trading sites, because technically, no money would be involved. If I open an account with LTC, and close it ETH, where's the laundering? I still can't go to a bank to deposit those altcoins.
