We already have the tools to stop this from happening today. The problem is not the technology but the fact that companies do not want to work together to fix it. It is sad that we let the internet break because people are too slow to use the safety features we have.
If a bunch of big tech companies started collaborating/colluding to implement this, we'd just have a bunch of people on HN decrying the "centralization" of the internet concentrated in the hands of a few.
This is decentralization in action. You have to take the good with the bad.
If "bad" is that things are only working 99.999% of the time, and every couple years someone borks their BGP config and fixes it in a few minutes, then bad sounds pretty good to me.
In large complex systems, perfection isn't really possible.
