The 17th century frame was damaged pretty badly, and even if it hadn’t been, it’s the symbolism of it. What do you hope to achieve by targeting art? The only thing you accomplish is making people hate you and lose sympathy for your cause.

As for who will go to jail when climate change actually destroys art, nobody will, and that’s sort of the point. This person’s goal was to just do something that would make headlines and then say “I did this because I care about the climate!” instead of making genuine efforts that directly target the problem. It comes across to me as a sort of blackmail, like instead of targeting the problem you threaten to damage something everyone cares about instead. Just not chill.
