Actually it is possible. It doesn't have to done on client-side. You can do it via DNS settings with Pi-Hole on your network, or create your own private tunnel with Pi-Hole. After that, you need to block subdomains with amp.. Or even you can create your own iOS app for it, and yes it is also possible.
By creating a extension which blocks AMP, for ourselves. But, if we really need to destroy AMP from internet. Unfortunately it is not really possible, unless if you have enough money to buy Google.
You are right. There are many Tier 1 networks so Internet can’t be destroyed easily. Even If internet dies there’s radio communication and other stuff. Like SATCOM.
