What you're alluding to is an encrypted messaging system. Sorry to inform you that those don't qualify as monetary assets because they're not worth anything.
Money is an inherently "non-private" medium. It reaches into every nook and cranny of economic life. Records of ownership are different and can be hidden from view. But for a monetary medium to worth anything it needs adoption and you can't cherry pick who adopts it. Its mechanics and audibility need to be accessible to all and sundry be that whoever it may. If you want to create an exclusive, closed ledger that's only accessible to those who happen to hold a private key then go ahead but you can kiss your adoption goodbye because all you've got then is an encrypted tunnelling system. Have a look at the existing content infrastructure on the internet to see where that fits in - this story has already been written. There are plenty of precedents as to how it gets played out.
Even if you did succeed in gaining widespread adoption for a cryptographically obscured blockchain, people are deluded if they think that's going to give them any "privacy". For it to be any use you need to exchange it for something that isn't another bunch of coins from the same blockchain and that's where it will be regulated.
So I don't agree with you that "privacy" can be prioritised over everything else. Adoption, value, ubiquity and confidence are far higher priorities because if people decide they want it because its valuable, they'll soon find ways to keep it private which is not the job of a monetary asset anyway.
Given that background though, Dash DOES put privacy as a far higher priority than anything else because it explicitly optimises fungibility without turning itself into a tech that's no more than a secure emailing service. Thats what you should be concerned with and thats why you've not had a single vote in support of
this proposal other than the two of your own
