While bad actors being punished is important, there is a constant trade-off for ensuring good actors aren't punished. Ideas like trial by jury and innocent until proven guilty try to address this because the judge of good and bad is essential. I assume you don't see government dissent as bad, because social credit and constant surveillance will discourage and punish these good actors. And with a system like this setup, more nefarious, corrupt, and oppressive uses could occur eventually. And with China known for its corruption and brutal authority, I am surprised you are so confident the government won't continuously abuse this power if not now than in the future.
