The point in adding DRM in JPEG is not to encrypt the image (we have encryption software for that, or ZIP with password), but rather allow to link metadata on copyright statements, ownership, license information of the picture etc to the actual JPEG file. Yes, it can be defeated by a simple screenshot, and it is even possible to strip off this data using a simple JPEG library. The important point is, that by taking this action, a person cannot claim he/she didn't know about the license that was present on this picture. The request to add DRM to JPEG was not something brought up in JPEG itself, but came from IPTC, EXIF, etc related organizations. It will be optional, and will not break the ability to view an image as-is. It is digital rights management, not copy-protection.
One more thing: I read a lot of BS about PNG is better than JPEG, or BPG beats bla bla. Let me say that all image formats have their strength and weaknesses. PNG is a lossless image coding format. It is pretty good at that. BPG is based on HEVC, so it is more a file format than an image coding standard. Does it matter? Probably not, but someone's wrong on the internet:) (Google the XKCD... too lazy).

I'm sorry, but it won't be anything like what you are saying. But who cares about informed opinion anyways?
