It's the opposite. Regulation assumes business will do anything they think they can get away with if it will make a buck. A lack of regulation assumes companies won't do those things.
People think "regulators" allowed this to happen, but actually as "regulators" are agencies established by the government that act upon law. At the time of the 2008 financial crash there were limited or few laws (i.e. regulations) on derivatives. It's law makers that refused to act.
It seems people are largely unaware of the myriad of regulatory changes that came after 2008 and bernie that applied to derivatives and customer/investor protection in general.
The same set of factors that created 2008 is no longer applicable as the environment has changed. There will surely be new regulatory weaknesses that need to be addressed
No that's a bad analogy because no one is arguing the water should be taken away because of a misguided understanding that it's inherently dangerous.
The actual analogy is "People have died in water, so no one should swim anymore"
But that's obviously absurd. You hire life guards, teach people to swim, get a life vest, life savers, etc
