The big difference here is that this was created by an act of Congress, not the result of a regulatory body straining at the limits of its remit. That makes it much more likely to survive administration changes or court challenges.
Even now the CAN-SPAM act feels outdated -- I do like the unsubscribe button, but I would like to see email verification made explicitly required. That in order to start emailing you, you need to send an initial engagement email saying that the organization wants to start emailing you, and requiring you to actively opt-in to emails rather than just start sending them.
This would both cut down on marketing spam as well as mistaken email addresses. Most reputable websites do email verification where you have to enter a code or click on a link, but I have a surprising number of emails that get sent to me even though I am not the person the emails were aimed at.
