Looking it from another point of view, it can also be that there is consider protection but instead of consirmer protection, as could say end user protection because there is no greater protection that the one you provide for yourself and that is what bitcoin offers but because we are used to a body providing such protection and major players in the indiutry too believes that because of the absence of central body to ensure that, they are free to do anything they want but we they can just do what is right, control in your hands is the best prorection.
Im verry confused on what you are trying to say. what protection are you talking about? bitcoin has no protection because as the op said above , 'bitcoin transactions are not ireversible' which means if you got scammed there is no chance that your coins will be recovered. Not unlike to other known payments like paypal that transactions can still be reverese because they have a chargeback policy to protect their users from scammer and other fraud activitites
