Personally, I've encountered difficulties in making anonymous transactions with ethereum. I was only able to find 1 (shady looking/centralized) mixer and a smart contract that almost nobody uses.

Led me to make a few payments in Monero/bitcoin (which has plenty of reputable mixers available) instead of ether which would've been my preference. So yea, IMO any increases in ethereum's fungibility will totally lead to immediate increases in value.

If anybody links me a good ethereum mixer, I'd be stoked.

I'm going to check out TX, sounds interesting.
