Agreed. The argument seems to be that the targeted pieces are "oil" paintings. But surely they know that the oil in these masterworks is derived from renewable sources and that therefore makes no sense, oil in oil paint is not petroleum based. So it seems the argument is disingenuous and there is a conspiracy. On the other hand I have realized that very few things people do are rational so the assumption common in economics theories that people are making rational choices I am not convinced by. Personally I think these people are all just crazy. However I can not rule out conspiracy to discredit. Like UFOs, this movement is an enigma.
