Suppose for a moment that the Equifax hack was carried out by a nation-state (like, say, North Korea). This is not an issue of consumer trust and safety. It is an issue of national (US) security and safety.
To give another analogy, imagine that in 1920, the Canadian military marched over the border and robbed some banks. Does it make sense for the patrons of that bank to be able to sue the bank? Maybe. It seems like that's less of an issue than the fact that Canada has seized assets that belong to US citizens.
My point is not that Equifax is innocent, or that the situation is being handled appropriately, but rather that this whole thing looks weird enough that there it's probably a lot worse (and more complicated) than we think it is.
