What a weird statement. Ideally 0% of policies would fail, since the goal of having a policy is to succeed. If you're opposed to any climate policy, you should wish for NaN% failed policies instead (i.e. no policies at all).

Aiming for 100% failed policies sound like a way to make everyone, including you, unhappy.

Public failed policies prevent or deter future failed policies. You must hope for failed policies to get to NaN% policies.
