Could an alternative DNS system fix this? Tor for DNS that both masked the lookup and the resulting IP would stop any type of filtering/blocking/take down etc? Coupled with https, to stop packet inspection?
We can't magic rogue institutions, politicians and laws away with maths. But it can have an impact on the practical damage they can do.
I can easily come up with 'engineering solutions' to solve social / political problems, but it's usually paired with some sort of social/political action (e.g. engineering cheap weapons to supply a violent revolution).
I would go the other way, engineering solutions (i.e Technology) dictate social and political problems.
