Earlier quoted context omitted.
Does this apply to nuclear weapons? To biological weapons? “Tool is expensive” is a real, effective deterrent to frivolous use of a tool. There’s a reason we pool resources into governments, which is explicitly so we (via a government) have capabilities that we (as individuals) don’t have.
No, but it does apply to the distribution of slippery slopes. The OP specifically said tools "like this"
While it’s convenient to dismiss any discussion about A and something slightly similar to A as “slippery slope,” an inconvenient fact is that the slope often is slippery. It’s increasingly evident to anyone paying attention that information warfare can yield disastrous effects in a variety of ways: disrupting peaceful transition of power; disrupting critical infrastructure; disrupting command and control of ”traditional” WMD systems, even.
So that’s sort of the spirit of my question: how far does this argument go? What is the definition of “like this?”
