> Up until thing like Firesheep and Snowden, and still to some extent, a lot of Internet traffic was only safe based on not passing any bad actors.
So what? "Only safe based on not encountering bad actors" is far and away the dominant mode of security everywhere. It's what keeps your house unburgled, your planes in the air, and your family alive. Breaking into a house, taking down a plane, and murdering strangers all require very little in the way of skill or planning. Burglary and murder are also unlikely to be caught (absent a connection to the victim).
