Alternatives include conforming to unjust laws, or violating openly and ending up imprisoned. Neither sound like fun. Or, yes, going somewhere else. But in my experience, there's really nowhere to go. So hey.
Mass surveillance is a direct violation of the fourth amendment, outlawing it completely is the only reasonable solution.
It's easy to cite the Fourth Amendment. But it's all in the interpretation. The War on Drugs arguably violates the Bill of Rights in numerous ways. But try telling that to a judge.
And anyway, as I frequently note, the NSA is a military COMSEC organization. And the US is perpetually at war. So the NSA ignores the Constitution and law. At best, it pretends respect.
Ok, without the VPN part.
In the former Soviet Union, there weren't VPNs, Tor and stuff. But there was samizat. And much conversation, fueled by vodka and bad cigarettes. It ended up working well enough. Except that Reagan, Bush and Carter went on to screw Russia so badly that it embraced Putin.
