No offense, but in all likelihood no one is attempting to counterfeit or pirate your Mom's videos and photos of your childhood, and ownership/p2p ownership transfers are not material.
There are almost infinite real world examples were ownership records are benefited by blockchain technologies over centralized services. Take property deeds, usually kept and recorded at the County level, there is almost endless fraud with people filing forged quitclaim deeds on a daily basis. That would be an example of a public record, but their are private record keeping examples such as stock certificates. Usually the "Dole" case is the most famous example, where you have a publicly traded company with all the benefits of corporate record keeping, stock trusts and banks, and centralized stock exchanges, but when the buyer went to take it private low and behold the public company with all the centralized safe guards in the world should have had a total capitalization of 36M shared but somehow had about 49M share issued, it only ended up in $150M in damages, but this could not have happened using blockchain and most agree nearly every publicly traded company likely would have the same inconsistencies.
