This is not a matter of "choice". It merely allows the reckless Wall Street behavior that led to the 2008 collapse to continue. If these "too big to fail" banks did fail, it would destroy the economy, which is why they were bailed out in 2008. What we should put an end to is the very banks that are too big to fail. No bank should ever be allowed to become that big, then we wouldn't have to deal with this problem in the first place.
