I believe blockchain will disrupt the above listed industries and then some. The people standing in its way are the traditionalist who believe they have a lot to lose,if blockchain tech is adopted in these industries. So they try to destabilize by cooking up a storm to drown it out but just like time they can't stop it or change it. About the stable coin use a mode of payment ,sbd is pegged to the dollar .It would be great if SBD takes up the role it would further strengthen its position in the cryptocurrency market ranking if it is adopted.
