Dash is user's choice. It can be anonymous, and you can choose to do business with companies that require KYC due to regulations. The partnership is merely to help companies that want to accept Dash, to do so while being KYC, etc, compliant. It's exactly like a merchant's relationship with their bank, vs a cash spending customer buying bread at a grocery store. One is known and the other is anonymous.
With cash, it works the same. If you are a business that works in the black market, then you simply never deal with banks, at least not before cleaning up your funds in some way. Dash is cash in every way, even how it enters and exits the "system".
And sorry, I was late to the party again, but I'm going to quote Tok, in case you missed him:
True but slightly delusional.
The world financial system could collapse tomorrow, Bitcoin could go to $100,000 and you would still be dealing in fiat - or at least some new denomination that wasn't crypto. Even by some miraculous act of God, all prices in all world economies were suddenly to be denominated in Bitcoin (as opposed to, say the IMF's SDR), you still wouldn't be using the blockchain to facilitate trades. You'd be using the same commercial technology layer that's in use right now and you can bet your bottom dollar that WILL be regulated.
Doesn't mean people can't still do blockchain-only trades that are genuinely anonymous though, but it just depends on whether you want to be uniquely stuck in that tiny minority sector of the economy or not.
The bold is me. Why corner crypto into a fringe subsection of society? My goal is to never hold Fiat for any length of time because it's an inflation nightmare. Yet the world still trades in Fiat, and will continue to do so for quite some time. Making the exchange between the two as seamless as possible is brilliant, and does not effect the performance of Dash as an anonymous pear to pear cryptocurrency.
