Therefore we should do nothing! Why should I do anything if the folks before and around me didn't already do everything? Moreover, why work on a climate catastrophe for everyone if there's even a chance of negative economic impact for the investor class?
You don't have to do anything. You're losing money if you don't move to solar. You don't have to do anything out of any kind of altruistic future world saving hopes and dreams.
You can just do it because you're cheap and greedy.
If you want to stand by and pollute the world with fossil carbon emissions... well you're paying extra for the privilege, and why?
