OK? Good! That's what I want to happen! I want that. I do not care if some weirdos on an anime image board can't access some image. I don't want my credit card maxed out.

Is that not a serious request? I play around in the same big-boy cloud as some SaaS company, but I'm on the free tier and I explicitly do not want it to scale up forever, and I explicitly do not want to destroy my credit or even think about having to call Amazon over a $100,000 bill because I set my shit up wrong or whatever. I want it to shut off my EC2 instance once it has used up whatever amount of resources is equal to $X.

Obviously any world with this feature would also feature customizable restrictions, options, decision trees, etc etc. I don't think anyone is or was suggesting that someone's SaaS app just gets turned off without their permission.
