Wait, so unless I can come up with an exactly perfect list that flawlessly prioritizes every possible action that humanity could ever undertake, then I'm not allowed to have any opinion whatsoever about whether any given action is more or less important than anything else? By that logic, we should never choose to prioritize anything over anything else, and we should just select all actions by pure random chance.

Clearly they didn't drop everything, but they are introducing a new regulation which is going to require resources to implement and enforce. Is preventing 2 seconds of lobster suffering the best use of those resource? I guess if we just have to randomly choose actions and we can't say one action is better or worse than another unless we can list the relative priority of all possible actions, then it doesn't matter.

We already have a system. We engage in reasoned debate where people observe what costs an action will have, and demonstrate how many people will be helped by it and they argue for why those benefits outweigh the costs. If your best defense of a given course of action is ¯\_(ツ)_/¯ people want weird stuff sometimes! Well, maybe that's not very convincing.
