Brief disruption of a single large-scale pollutant out of a million more just like it, before being thrown in jail for decades on terrorism charges, is not "actual disruption". Statistically it doesn't even rise above random noise in terms of effect, and people would hate them more, not less. They would be branded violent terrorists trying to destroy our infrastructure. You would be sacrificing everything and all other forms of effectiveness to have the tiniest, barely-detectable impact on the root issue.

The problem is systemic, and so must be the solution. You cannot break a system by destroying one of a million nodes in the system. If we had the power to stop this via direct action, we would have already long been capable of solving this with political action well before that point.
