Earlier quoted context omitted.
The history of technology, including weaponry, has been to increase the power of the individual with respect to the state.
pray tell how does the individual counter the state's use JDAMs?
On the other hand, for the state to use JDAM against the individual, they need to know that said individual is there and is worth targeting, for starters.
I don't think it's accurate to say that the balance of power has shifted on the whole, but regular individuals definitely have access to way more destructive power than they ever had in history. At the same time, modern military technology, while very destructive, is also very demanding in terms of logistics. Even a single blown up railroad, fuel depot, large transformer etc can have a profound effect.
The destructiveness isn't always a positive, either. Any modern military can easily reduce even a very large city to rubble, but to what purpose? A city is only valuable in the grand scheme of things because of its infrastructure and its population that can utilize that infrastructure for some useful economic purpose.
