I think the amount of money involved is getting large enough to hold some people (at least moraly) accountable of something goes wrong. And I think this also holds for not speaking up.
I think one of the really great things about Bitcoin from a philosophical / ideological point of view is that due to its decentralized nature, it returns responsibility and power to the individual. There's no company, no bank, no government that is responsible for Bitcoin, and no single individual or small group of individuals. It's a very large group of individuals - and anyone doing anything with Bitcoins (even talking about it) is part of that very large group.
So it's the
real thing: Everyone is fully responsible for their own actions. One really nice thing about Bitcoin is that it's fully transparent - from the core concepts to the individual transactions to the client source code (and since it's a P2P network, there's no secret server, only equal clients ;-) ). So, what you do with Bitcoins and the consequences you have to face of what you do with Bitcoins are fully up to you. If someone feels they don't understand what's going on: Educate yourself, do the research, ask specific questions.
If someone feels they want to hold someone else accountable for their own actions (i.e. whether or not you buy and use Bitcoins or not), they're clearly not ready for this new age of which Bitcoin is a part of. In that case, it's probably best for you to stay in the illusion of powerlessness and blaming governments and banks for the financial desasters (and wars), and oil companies and Tepco (and the likes) for the destruction of our planet ... or big pharma for the destruction of our health - while in reality it's "most people" who gave those "evil greedy institutions" their money and power to do what they do (much of which I personally consider "seriously criminal" by the highest standards). IMHO, it's time for people to wake up and reclaim their own power and responsibility - step by step. It's kind of hard and usually not wise to try to drop out in one big step immediately - it's much more realistic to sustain by taking small steps, considering each step carefully before taking the next.
And Bitcoin clearly helps with that. IMHO, this is actually even kind of built in. Another thing that clearly helps, of course, is buying stuff from companies you did a little research on and did your best to find those that don't operate on greed but motives that are truthfully supporting life. And, equally important, working for (i.e. supporting) companies that you feel deserve your creative energy and make good use of it. Or completely do your own thing ;-)
