Laws and regulation should never be to specific. You give very specific guidelines and times, such as 8 years, 50% of etc.

Principles would be formulated differently. I'd prefer something along the lines like:

Before remastering, let a game mature.

Cherish the initial release, archive it and keep it available.

Take care when remastering a game, to be true to the original, include a switch in the options if possible.

Etc.... maybe improved wording.

Laws and regulation would be much better if they were specific. It is just that people making laws and regulation are usually too lazy to do so or just want to be able to interpret them how ever they want afterwards.
