majamina I'm going to play devil's advocate with you, so bear with me here.
No, because your transaction is easily traceable through the blockchain.
Easily? If all I want is to obfuscate I can send it to myself 1000 times through various transaction splitting and recombining, and I can send it it and out of exchanges. I can even setup a BitPay account and pay myself for fake goods. If every step in my self-mixing path has a 50/50 chance of being mine then a mix of 1000 steps plus some exchanges and BitPay is 1010 steps for example. So the chance of figuring out its me is 2 to the power of 1010. Google says that your chance of deanonymising me is 1 in 10 to the power of 304. I saw some 10 to the power of 40 numbers thrown around earlier, so are we safe in saying that Bitcoin can easily be made 7 times more private than Dash?
Well, if you get away with it, then that transaction is 'funged' yes. But 'BitcoinFog' is a trusted mixing service that could be keeping logs, reporting up to your adversary or creating some other shitstorm that you might not care to weather.
MasterNodes are also a trusted mixing service. How do you as a user prove that the MasterNodes you use not keep logs or aren't reporting to some adversary?
yes it does, that is the critical point. If you can mix the coins at will, in a trustless and sufficiently secure manner then there's your fungibility.
Security I'm less worried about, but how are MasterNodes trustless? I know, I know, there's a 1 in 10 to the power of something chance, but then why not just use Bitcoin? If you think that a 35 year old neck-beard living in his mother's basement can secure his MasterNode that is quite worrying. I never thought about it in those terms until a few hours ago. Read this and then tell me if you think that even an advanced MasterNode operator can keep it secure:

I do respect what Evan is trying to achieve but this thread has opened my eyes. Just in the past 24 hours I have read about how
British Airways got hacked and
Slack got hacked for days, and
Nigeria's Electoral Commission website got hacked. If powerful organisations can't secure their servers what makes you think that 2,000 MasterNode operators will be any different?
