We should be talking about the more abstract problem of asymmetric defense and offense.

Imagine that nukes were easy to make with household items. That would be a scenario where offense is easy but defense is hard. And we would not exist as a species anymore.

Once a hypothetical technology like this is discovered one time, it's not possible to put the genie back in the bottle without extreme levels of surveillance.

We got lucky that nukes were hard to make. We had no idea that would be the case before nuclear physics was discovered, but we played Russian Roulette and survived.
