Well, they also "created" this market. More than 90% of the miners wouldn't be there if speculators did not exist.
To contradict something my mother used to tell me: Just because you created something doesn't mean you have the right to destroy it. Murder is murder, even if you're killing your own child.
Speculation within certain bounds is a good thing, without active speculation we wouldn't have Forbes and SmartMoney writing articles about us, but too much speculation allowed to run rampant and create bubbles as massive as this past week has seen create collapses like we saw on Saturday and I for one don't want to see any more collapses that big. It is therefore in everyone's best interest to understand what 1 BTC *should* be trading at and refuse to participate in such speculations. There will always be those who will and small inflationary bubbles and their associated crashes can still occur - I welcome them even, because they mean more investors coming to our community - but we can't allow them to get out of hand like they recently have.
I'm not talking regulation or enforcement, I'm talking education. People are still welcome to make their own decisions, but I'd like them to be well-informed decisions.
