In short, it hurts the product's transparency. Users don't really understand who gains and loses by its adoption. Gold bugs hoard gold because they don't trust the government. Maybe I'd be a dollar bug and hoard dollars because I don't trust Satoshi (or trust him less than the Fed). But I can't even figure out if I don't trust Satoshi or not because nobody knows who he is and what his/her/their long/short term intentions with the alleged $100M bitcoins Satoshi controls.
No one cares if he will make $100M from this or not. $100M is less than %10 of the total value of all the bitcoins currently in the market and we can just think of that %10 as the one-time tax "humanity" paid to get the bitcoin system developed.
Well, that's just it. I trust the blockchain (and other open source methods), but not Satoshi. i.e. when it becomes easier to use cryptocurrencies, I'll use dogecoin, litecoin, or something else.
However, right now, they just seem too hard to use. And solutions that are easy to use, like non-bank banks such as Mt Gox, well you know how that turned out.
