It’s very easy to make digital copies of physical media. The resulting copy is likely to be as high quality as you can find, and as portable as any digital copy can be. Pop it in a folder and point Jellyfin at it, and it’s available anywhere.

I can’t find the text of the new law in 5 minutes of searching, but from looking at a variety of reports, it seems like this law removes loopholes that were being used to get parental permission for marriages involving children. I suspect they just wrote it this way because the bulk of the issue is older men marrying teenage girls, and that is a thing it does ban.
