You framed the question. Don't push the goal posts around by pointing to past autocracies. It might be a very small risk, but it is infinitely bigger than the risk from my own govenment - where the risk is zero.
Sure. But the original question was: do you think that that should worry regular folks more than the evil and abuse perpetrated by their own government?
However, communist governments have done that to millions. If you don't see the difference, I suggest you reexamine your principles.
