I don't think that's how the law works. There's a fair use exemption for using copyrighted material, however you're still not allowed to bypass DRM to get at the data.
> The 2021 exemptions, issued in October 2021, are for:[15]
> Motion pictures (including television shows and videos), as defined in 17 U.S.C. 101, where circumvention is undertaken solely in order to make use of short portions of the motion pictures for the purpose of criticism or comment, for supervised educational purposes, to accommodate for accessibility for disabled students in educational institutions, for preservation of the motion picture by a library, archive, or museum, or for research purposes at educational institutions;
No, a version of that exemption was first added in 2010. Each exemption has to be readded every new listing.
And that exemption only adds cases in which stripping DRM from a DVD becomes legal. It's still generally illegal, and most people using makemkv are likely using it illegally.

I'm not sure this has ever been tested in court, though. And even the DMCA itself does provide for a rather clunky system of "exemptions" to the no-circumvention provision.
