> Without winterization, it doesn't matter if Texas is connected or not. With it, it doesn't matter either, because it produces and uses so much electricity.
Isn't this just more argument for perfection. Sure, if they completely and fully winterized every single plant, it wouldn't be a problem. But what if they did more than nothing to winterize but less than 100%. Then imagine they were connected as well. If they had simply done better at multiple things, they wouldn't have to be perfect at any one thing. And it certainly doesn't excuse them making terrible decisions on multiple things.
Sure, if everything in my house is 100% fireproof, I don't need a fire extinguisher. Sure, if everything in my house is made out of kindling, a fire extinguisher is going to be inadequate protection. But if I build my house out of relatively fire retardant materials and I keep a fire extinguisher, I am likely going to be ok. Perfection is the enemy of good, and is no excuse for just settling for outright bad.
