Still waiting for Manamina's reply to my previous argument...
Let me rephrase: Due to the nature of a transparent blockchain, there will always be associations with addresses, even if your concerned association is eliminated. People won't mix because they don't think they need to, or maybe they aren't aware of some illicit trade 80 transactions up-chain. Because of this, we will still see increasing use of blockchain analysis and increasing discrimination against transactors that leads to fungibility issues. The only way to eliminate this concern is through an entirely opaque block chain.

Busy day, no time to post, just as well since I 'killed the thread'
Anyway, you made a great point here. I guess the answer is that DASH is optionally fungible. You can mix balances if you want and nobody can prove there is any association between your mixed addresses and someone else's. I agree this means users could forget and end up with dodgy associations by accident or whatever.
I also agree that XMR is more fungible....pretty much totally fungible! However, I don't think that what you originally said is true - i.e. that all DASH ends up tainted. There would be too much ambiguity in the blockchain introduced by widespread mixing. Blockchain analysis tools would frequently hit 'dead-ends'.
Okay. Then in my opinion, yes, it's probably fit for purpose right now. But as demand for blockchain analysis services increases, major fungibility issues will start to pop up. Of course this won't be provable until it actually happens.
Fair comment. The coin is still in development...will be interesting to see how these arguments stack up over time.
