My argument is the option you're omitting:

d) animals suffer, we should care, but we should not pass laws when their sole purpose is to prevent that suffering.

There is more to a society that what it compels at gunpoint. We can abhor behavior without proscribing it by law.

What is law if not the ability to arrest controversy?

[wildmusings]

Are you arguing that the solution to all controversy is to pass a law? You are proposing to solve all problems at gunpoint.

What space for different conceptions of the good, for diversity of values and preferences, could exist in such a society?

You must have limiting principles for when we should resort to the remedy of the law. Perhaps yours are different than mine, but I doubt that you have none at all.
