You're talking nonsense and don't even understand the point of DRM.
It's not to keep third parties from using the content, it's to keep
the intended recipient from using the content. Crypto INHERENTLY
CANNOT do this because it's logically nonsense. The only way it can be
done at all is by changing the intended recipient to some "trusted"
(aka malware) program on the real recipient's machine, and having that
program obfuscate things to keep the recipient from getting the
content in a usable form.

The law you're calling for simply outlaws DRM. There's no way to have
DRM without proprietary lock-in.
