I'm tempted to consider the logistics of the idea. The rule of law, and the expectation that society's problems won't be solved through violence, are important pillars of our civilizations and shouldn't be discarded lightly. On the other hand, there's a very real possibility that climate change will destroy our civilization. When the greater good is "avoid the death of billions"... then yeah, private illegal action is starting to look good. Not that good. If you look at the fact that associations like Greenpeace that were built on doing what OP suggests have probably offset the development of nuclear power by decades, and gotten us that much closer to global disaster, you realize that direct activism can have bad consequences too. But good enough I wouldn't dismiss it out of hand.
